Specifications
■Ratings/Characteristics
Note: 1. Do not use an Inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power
Supply may result in ignition or burning.
2. Refer to Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models) on page 11 to 13 for details.
3. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than +20% of the voltage adjustment range. If the adjuster is turned too far, it may
activate the overvoltage protection function and interrupt the output.
When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.
4. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.
5. Conducted emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under
the Power Supply. For 15-W models, insert a clamp filter (ZCAT2436-1330 by TDK: 50 Ω min. [50 to 500 MHz], or the equivalent) in the output wire to reduce noise.
6. Radiated emissions: The noise value is affected by factors such as the wiring method. The Power Supply conforms to Class B when the aluminum plate is laid under the
Power Supply. For 150-W models, insert a clamp filter (ZCAT2017-0930 by TDK: 35 Ω min. [50 to 500 MHz], or the equivalent) in the input wire to reduce noise.
7. The weight indicated is for bottom mounting, open-frame models.

Engineering Data (15-W, 30-W, 50-W, 100-W, 150-W Models)
■Derating Curve
300W/600W/1,500W
Note: Refer to page 17.
Note: 1. Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the area shown by
shading A in the above graphs).
2. If there is a derating problem, use forced air-cooling.
3. When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Multiple 100- and 150-W models cannot be used
side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference value, allow at least 50 mm spacing
on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less.
4. When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curves.

■Mounting
Note: 1. Improper mounting will interfere with heat dissipation and
may occasionally result in deterioration or damage of inter-
nal parts.
Use the Power Supply within the derating curve for the
mounting direction that is used.
2. Use the metal plate as the mounting panel (*1).
3. Install the Power Supply so that the air flow circulates
around the Power Supply, as the Power Supply is designed
to radiate heat by means of natural air flow.
4. Mounting screw tightening torque
(recommended value: M3 (0.49 N·m))
■Remote Sensing Function
(S8VM-100@@@@/150@@@@ only)
This function compensates a voltage drop on the load lines.
To use this function, connect after removing the two short bars of the
remote sensing terminal.
Note: 1. Use a 2-conductor shielded cable as a connection wire (*1).
2. Use as thick a wire as possible since high voltage drops on
the load lines (*2) may activate the overvoltage protection
function.
3. Use when the voltage drop is 0.3 V or lower.
4. When the +S and −S terminals are opened with the short
bar removed, the overvoltage protection function is activat-
ed and the output voltage will be cut off.
5. If the load line is too long, use an electrolytic capacitor in the
following 3 locations:
1) Across the load terminals
2) Between the +S terminal and + terminal
3) Between the −S terminal and − terminal
Select the capacity of the connected capacitor from be-
tween several tens to several hundreds of μF as a guide,
and then determine the capacity when actually connecting
the capacitor between terminals as shown below.

Reliability
(MTBF)
135,000 hrs

MTBF stands for Mean Time Between Failures, which
is calculated according to the probability of accidental
device failures, and indicates the reliability of a device.
Therefore, it does not necessarily represent the life of
the Power Supply.
Life expectancy 10 yrs. min. The life expectancy indicates average operating hours
under the ambient temperature of 40°C and a load
rate of 50%.
Normally this is determined by the life expectancy of
the built-in aluminum electrolytic capacitor.

■Overload Protection
The Power Supply is provided with an overload protection function
that protects the Power Supply from possible damage by short-circuit
and overcurrent.
When the output current rises above 105% min. of the rated current,
the protection function is triggered, automatically decreasing the out-
put voltage. When the output current falls within the rated range, the
overload protection function is automatically cleared.
The values shown in the above diagrams are for reference only.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or other overcurrent state continues dur-
ing operation.
Do not continue an overload state for longer than 30 sec-
onds. Eliminate the overcurrent state as soon as possible.
2. Internal parts may possibly be deteriorated or damaged if the
Power Supply is used for applications with frequent inrush cur-
rent or overloading at the load end. Do not use the Power Supply
for such applications.
■Overvoltage Protection
Consider the possibility of an overvoltage and design the system so
that the load will not be subjected to an excessive voltage even if the
feedback circuit in the Power Supply fails. When an excessive
voltage that is approximately 140% of the rated voltage or more is
output, the output voltage is shut OFF, preventing damage to the load
due to overvoltage. Reset the input power by turning it OFF for at
least three minutes and then turning it back ON again.
The values shown in the above diagram are for reference only.
*1 S8VM-@@@24A@/P@
*2 Except for S8VM-@@@24A@/P@
Note: 1. Do not turn ON the input power again until the cause of the
overvoltage has been removed.
2. The overvoltage protection function may be activated when
the output voltage adjuster (V.ADJ) is set to a value that
exceeds +20% of the rated output voltage.
3. When the +S and −S terminals are opened with the short-
bar removed, the overvoltage protection function is
activated and the output voltage will be cut off.
■Undervoltage Alarm Function (Indication and Output)
(Only S8VM-@@@24A@/P@)
If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an
output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@).
Transistor Output: Sinking type: (NPN) (S8VM-@@@24A@)
Sourcing type: (PNP) (S8VM-@@@24P@)
30 VDC max., 50 mA max., Residual voltage when ON: 2 V or less, Leakage current when OFF: 0.1 mA or less
•Undervoltage Alarm Function 1 (DC LOW1)
Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V
lower than the voltage output at an output voltage of 24.0 V).
During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is
used as a latch holding function.)
•Undervoltage Alarm Function 2 (DC LOW2)
Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V).
During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights.
Note: 1. This function monitors the voltage at the Power Supply output terminals.
To check actual voltage, measure voltage on the load side.
2. Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1).
3. Once a voltage drop in the output voltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status
of the LED (6: Yellow) light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON
again.
4. If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output
hold status for detection may be reset.

Probable cause of error Troubleshooting methods
--- --- 1
A momentary power failure has occurred in the
input.
Check that the output voltage is normal and no problems have occurred in other devices. No problems
will be caused by continuing to use the Power Supply as is. To clear DC LOW1 (LED display and tran-
sistor output status), turn OFF the input power, and wait at least 60 s before turning ON the input Power
Supply again.
2
A momentary overload has occurred. The load current has probably exceeded the rated current. We suggest reducing the connected load
or replace the Power Supply with one that has a higher capacity.
A momentary output voltage drop has occurred
at startup due to the capacity of the capacitive
factors on the load side or when the load is acti-
vated.
A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power
Supply with one that has a higher capacity.
The output voltage has returned to normal volt-
age following a rapid drop caused by using the
output voltage adjuster (V.ADJ).
Turn OFF the input power, and wait at least 60 s before turning ON the input power again to clear the
indicator status.
Deterioration due to age (when the Power Sup-
ply has been used for several years)
The internal parts of the Power Supply may have deteriorated due to age. We suggest replacing the
Power Supply. Also replace other Power Supplies that were purchased at the same time.
3
Overload (immediately following first use of the
Power Supply or when increasing the load)
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
The output voltage dropped to -10% or lower of
the rated voltage resulting from using the output
voltage adjuster (V.ADJ)
Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ).
A sudden overload occurred and the Power
Supply remains in overload status.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device. Continued use in overload status may damage the Power Sup-
ply.
4
The output voltage remains low after a rapid
voltage drop caused by using the output voltage
adjuster (V.ADJ).
Adjust the output voltage to the rated values using the output voltage adjuster (V.ADJ). To clear DC
LOW1 (LED display and transistor output status), turn OFF the input power, and wait at least 60 s be-
fore turning ON the input power again.
The overload status continues to fluctuate fol-
lowing a sudden overload.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device. Continued use in overload status may damage the Power Sup-
ply. 5
Deterioration due to age (after using the Power
Supply for several years)
The internal parts of the Power Supply may have deteriorated due to age. Replace the Power Supply.
Also replace other Power Supplies that were purchased at the same time.
6
Overload (immediately following first use of the
Power Supply or when increasing the load)
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
Power Supply interrupted or damaged. Check whether the input power is being applied correctly. If there is no output even though the input
power is applied correctly, the internal circuit is probably damaged.
7
Overvoltage protection operation Turn OFF the input power, and wait at least 3 min before turning ON the input power again. If the same
status recurs, the internal circuit is probably damaged.
The short bar has fallen off, or the +S and -S ter-
minals are open.
Check whether the +S and -S terminals are open. If so, the overvoltage protection function is activated.
Therefore, turn OFF the input power and wait at least three minutes before turning it ON again. (S8VM-
10024A@/P@ and S8VM-15024A@/P@ models only)
Output short-circuit Remove the cause of the output short-circuit.
Intermittent operation due to overload (S8VM-
01524A@/03024A@ only)
The load current has probably exceeded the rated current. Check the actual load current and Power
Supply capacity. Continued use in overload status may damage the Power Supply.
8
The Power Supply fails to start repeatedly due
to the capacity of the capacitive factors on the
load side.
A large inrush current has probably flowed to the load side at startup. We suggest replacing the Power
Supply with one that has a higher capacity.
The input turns ON and OFF repeatedly. Check whether the Power Supply’s input voltage is being applied correctly.
The status repeatedly switches between normal
operation and output short-circuit.
An error has probably occurred in the load device. Turn OFF the input power, and check whether any
errors have occurred in the load device.

Engineering Data (300-W, 600-W, 1,500-W Models)
■Derating Curve
300W/600W/1,500W
Note: 1. Internal parts may occasionally be deteriorated or dam-
aged. Do not use the Power Supply in areas outside the de-
rating curves (i.e., the area shown by shading A in the
above graph).
2. When mounting two or more Power Supplies side-by-side,
allow at least 20 mm spacing between them. Always provide
at least 50 mm of mounting space for the surface with the
fan mounted. Be sure to provide at least 50 mm (S8VM-
300@@C/600@@C) or 100 mm (S8VM-15224C) of mount-
ing space on the opposite side of the surface with the fan
mounted.
3. When using the 1,500-W model for a long period of time at
an input voltage of 90 VAC or lower, reduce the load to 80%
or less of the above derating curve.
4. The ambient temperature is specified at a location 50 mm in
front of the center of the Power Supply's front panel.
■Mounting
Standard Mounting
Horizontal Mounting
Upside-down Mounting (S8VM-15224C Only)
Side Mounting
Note: 1. The internal parts may occasionally deteriorate or be bro-
ken due to adverse heat dissipation depending on the
mounting status. Do not use the Power Supply in any
mounting direction other than those specified.
2. Use the metal plate as the mounting panel (*1).
3. To ensure sufficient cooling, do not cover the air holes locat-
ed on the side the fan is mounted and the opposite side.
4. Mounting screw tightening torque (recommended value: M4
(1.27 N·m))
The screws must not protrude more than 6 mm inside the
Power Supply.
■Remote Sensing Function
Use remote sensing to automatically compensate for voltage drops
on the load lines. Connect the +S pin (pin 2 on CN) to the positive
load terminal and the −S pin (pin 4 on CN) to the negative load termi-
nal to enable remote sensing. When not using the remote sensing
function, use the standard supplied connector. The +S and +V pins
(pin 1 on CN) and the −S and −V pins (pin 3 on CN) will be con-
nected.
Note: 1. Use 2-conductor shielded cable as connection wire (* 1).
2. Use as thick a wire as possible since high voltage drops on
the load lines (* 2) may activate the overvoltage protection
function.
3.
Do not allow the voltage drop on the load line to exceed 0.3 V.
4. If the sensing line is too long, it is necessary to put an elec-
trolytic capacitor across the load terminals. The electrolytic
capacitor may generate heat due to the ripple current, de-
pending on connected load. Therefore, the electrolytic ca-
pacitor must have a ripple current allowance higher than the
output ripple current.
5. The stability and accuracy of the output will deteriorate if the
short bar is missing or if the +S and −S pins are open. Al-
ways connect the +S and −S pins.
6. Remove the standard supplied connector and prepare a
connector harness separately.

■Remote Control Function
This function turns outputs ON and OFF using an external signal
while input voltage is applied, using the +RC pin (pin 7 on CN) and
the -RC pin (pin 8 on CN). Connect a switch or transistor to the +RC
and -RC pins to use the remote control function. When not using this
function, the +RC and -RC pins are shorted by using the standard
supplied connector.
Maximum input voltage: 12 V max.
Maximum allowable reverse voltage: −1 V max.
Sink Current: 3.5 mA
Note: 1. Use 2-conductor shielded cable or twisted-pair cable as
connection wire.
2. The remote control circuit is isolated from the input and out-
put circuits of the power supply.
3. Remove the standard supplied connector and prepare a
connector harness separately.
■Power Failure Alarm Function
The power failure alarm indicator will light red to indicate an output
voltage error if overload, overvoltage, or overheat protection is acti-
vated, if a drop in the input voltage causes the output voltage to drop,
if the built-in fan motor stops, and during remote control standby. The
alarm is also output externally by a transistor.
Transistor output: 30 VDC max., 50 mA max.
Residual voltage when ON: 2 V max.
Leakage current when OFF: 0.1 mA max.
Alarm detection voltage: Approx. 80% of output voltage setting
During detection, the transistor is OFF (with no continuity across pins
11 and 12 on CN), and the LED (red) lights.
Note: 1. This function monitors the voltage at the power supply out-
put terminals. To check actual voltage, measure the voltage
on the load side.
2. Outputs are forced OFF if the built-in fan motor stops
(S8VM-15224C only).
3. Remove the standard supplied connector and prepare a
connector harness separately.
■Inrush Current, Startup Time,
Output Hold Time
Note: A maximum input surge current of approx. 40 A will flow at
startup even when not turning ON the input. Consider this
surge current when selecting the input switch, input breaker, or
external fuse.

■Reference Values
■Overload Protection
The Power Supply is provided with an overload protection function
that protects the Power Supply from possible damage by overcurrent.
When the output rises above 105% of the rated current, the protec-
tion function is triggered, automatically decreasing the output volt-
age.
S8VM-300@@C/600@@C
When the output current returns within the rated range, overload pro-
tection is automatically cleared.
S8VM-15224C
Outputs are interrupted if an overload continues for 5 seconds or
more. To reset the Power Supply, leave the input power OFF for more
than 3 minutes and then turn it ON again. Alternatively, turn OFF and
ON the remote control signal.
The values shown in the above diagrams are for reference only.
Note: 1. If the Power Supply has been short-circuited or supplied
with an overcurrent for longer than 30 seconds, the internal
parts of the Power Supply may occasionally be deteriorated
or damaged.
2. The internal parts may possibly be deteriorated or dam-
aged. Do not use the Power Supply for applications where
the load causes frequent inrush current and overload.

is calculated according to the probability of accidental
device failures, and indicates the reliability of a device.
Therefore, it does not necessarily represent the life of
the Power Supply.

■Overvoltage Protection
Consider the possibility of an overvoltage and design the system so
that the load will not be subjected to an excessive voltage even if the
feedback circuit in the Power Supply fails. When an excessive volt-
age that is approximately 140% of the rated voltage or more is out-
put, the output voltage is shut OFF, preventing damage to the load
due to overvoltage. Reset the input power by turning it OFF for at
least three minutes and then turning it back ON again. Alternatively,
turn OFF and ON the remote control signal.
The values shown in the above diagram are for reference only.
Note: 1. Do not turn ON the input power again until the cause of the
overvoltage has been removed.
2. The overvoltage protection function may be activated when
the output voltage adjuster (V.ADJ) is set to a value that ex-
ceeds +20% of the rated output voltage.
■Overheat Protection
The overheat protection circuit will operate and outputs will be shut
OFF to protect the Power Supply if the ambient temperature rises,
the fan stops, or other errors cause the Power Supply's internal tem-
perature to rise. To reset the Power Supply, leave the input power
OFF long enough for the Power Supply to cool sufficiently and then
turn it ON again. Alternatively turn OFF the remote control signal
long enough to cool sufficiently and then turn it ON again.
■Peak Output Current
(S8VM-30024C/60024C/15224C Only)
The peak current must satisfy the following conditions. Reduce the

Safety Precautions
Refer to Safety Precautions for All Power Supplies.
■Precautions for Safe Use
Mounting
Ensure sufficient heat dissipation when installing the Power Supply
to increase its long-term reliability.
Use the metal plate as the mounting panel.
When cutting out holes for mounting, make sure that cuttings do not
enter the interior of the Power Supply.
The amount of installation spacing required between Power Supplies
depends on the capacity. Refer to the following table.
15/30/50/100/150-W Models
Natural cooling is used, so mount the Power Supply so that there is
airflow around it.
Improper mounting will interfere with heat dissipation and may occa-
sionally result in deterioration or damage of internal parts. Use the
Power Supply within the derating curve for the mounting direction
that is used.
The internal parts may possibly be damaged if mounting screws are
over inserted. Refer to Dimensions on page 21 to 21 for maximum
depth of insertion inside the Power Supply.
Note: If more than one S8VM-100@@@@/150@@@@ Power Supply
is mounted together, install them as far away from sources of
heat as possible. If only 20 mm of space is available on the right
and left sides of a Power Supply (see note 2.), use the Power
Supply at a load ratio of 80% or less.
300/600/1,500-W Models
A forced-air cooling method with a fan is used. To ensure sufficient
cooling, do not cover the air holes located on the side the fan is
mounted and the opposite side.
Improper mounting will interfere with heat dissipation and may occa-
sionally result in deterioration or damage of internal parts. Do not
use the Power Supply in any mounting direction other than those
specified.
The internal parts may possibly be damaged if mounting screws are
over inserted. The screws must not protrude more than 6 mm inside
the Power Supply.
Note: 1. Convection of air
2. 50 mm or more
3. (S8VM-300@@C/600@@C): 50 mm or more
(S8VM-15224C): 100 mm or more
4. 20 mm or more
5. Use a metal plate as the mounting panel.
Wiring
Connect the ground completely. A protective earthing connection
stipulated in safety standards is used. Electric shock or malfunction
may occur if the ground is not connected completely.
Minor fire may possibly occur. Ensure that input and output terminals
are wired correctly.
Do not apply more than 100-N force to the terminal block when
tightening it.
Be sure to remove the sheet covering the Power Supply for
machining before power-ON so that it does not interfere with heat
dissipation.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not disassemble, modify, or repair
the Product or touch the interior of the Product.
Minor burns may occasionally occur. Do not touch the
Product while power is being supplied or immediately
after power is turned OFF.
Fire may occasionally occur. Tighten terminal screws to
the specified torque.
15-, 30-, 50-, 100-, and 150-W models (1.6 N·m)
300-, 600-, and 1,500-W models (M4; 1.6 N·m,
M5; 2.50 N·m, M8 bolts and nuts; 10.8 N·m)
Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not allow any pieces of metal or
conductors or any clippings or cuttings resulting from
installation work to enter the Product.

Use the following material for the wires to be connected to the S8VM
to prevent smoking or ignition caused by abnormal loads.
Over heating or fire can result from inadequately sized wiring
materials when problems occur at the load. As a general rule, always
select wire sizes suitable for at least 1.6 times the rated current.
Refer to the wiring manufacturer's recommended allowable current
and voltage drop specifications for information when selecting wiring
materials.
Recommended Wire Sizes
The current rating for the output terminals on the S8VM-300@@C is
40 A per terminal. The current rating for the output terminals on the
S8VM-600@@C is 60 A per terminal. Use two terminals together if a
current exceeding the terminal rating is used.
Use min. 60°C or 60/75°C wire.
Use copper conductors only.
Undervoltage Alarm Output Connector
Harness Manufacture Method
The following products are provided with the S8VM-05024A@/P@,
S8VM-10024A@/P@ and S8VM-15024A@/P@ for the undervoltage
alarm transistor output wiring.
Be sure to prepare the connector according to the following instruc-
tions to ensure correct wiring. For details, refer to the JST catalog.
•Use a wire size of AWG28 to AWG22.
•The guideline for the length of sheath to be stripped from the wire is
2.1 to 2.6 mm.
•Use either a YC or YRS Crimping Tool (manufactured by JST) to
crimp the terminal and wire.
•Be sure to insert the crimped terminal wires into the housing fully
until a click is heard. Also, make sure that the wires attached to the
housing are securely locked in place.
Signal I/O Connector Harness
Manufacture Method
The S8VM-300@@C/600@@C/15224C are using PHD connector
(manufactured by JST).
Be sure to prepare the connector according to the following instruc-
tions to ensure correct wiring. For details, refer to the JST catalog.
•Use a wire size of AWG26 to AWG22.
•The guideline for the length of sheath to be stripped from the wire is
2.3 mm.
•Use a YC Crimping Tool (manufactured by JST) to crimp the termi-
nal and wire.
•Applicable wire per barrel size is UL1007 (standard wire) and its
equivalent standard wire can be used. Use UL1061 or its equiva-
lent standard wire for AWG22 wires, because the wire insulation
outer diameter of UL1061 is small.
•Be sure to insert the crimped terminal wires into the housing fully
until a click is heard. Also, make sure that the wires attached to the
housing are securely locked in place.
Installation Environment
Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far away as
possible from contactors or other devices that are a vibration source.
Install the Power Supply well away from any sources of strong, high-
frequency noise and surge.
Operating Life
The life of a Power Supply is determined by the life of the electrolytic
capacitors used inside. Here, Arrhenius Law applies, i.e., the life will
be halved for each rise of 10°C or the life will be doubled for each
drop of 10°C. The life of the Power Supply can thus be increased by
reducing its internal temperature.
Ambient Operating and Storage
Environments
Store the Power Supply at a temperature of −25 to 65°C and a
humidity of 25% to 90%.
The Internal parts may occasionally be deteriorated or damaged.
Do not use the Power Supply outside the derating range (i.e., under
conditions indicated by the shaded area ( ) in the derating
curve diagrams on pages 11 and 15.)
Use the Power Supply at a humidity of 30% to 85%.
Do not use the Power Supply in locations subject to direct sunlight.
Do not use the Power Supply in locations where liquids, foreign
matter, or corrosive gases may enter the interior of the Power Supply.
Overload Protection
If the Power Supply has been short-circuited or supplied with an
overcurrent for longer than 30 seconds, the internal parts of the
Power Supply may occasionally be deteriorated or damaged.
Internal parts may possibly be deteriorated or damaged if the Power
Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such
applications.
Dielectric Strength Test
If a high voltage is applied between an input and the case (PE/FG), it
will pass though the LC of the built-in noise filter and energy will be
stored. If the high voltages used for dielectric strength testing are
turned ON and OFF with a switch, timer, or similar device, impulse
voltage will be generated when the voltage is turned OFF and
internal parts may possibly be damaged. To prevent the generation
of impulse voltages, reduce the applied voltage slowly with a variable
resistor on the test device or turn the voltage ON and OFF at the
zero-cross point.
When performing the test, be sure to short-circuit all the output
terminals to protect them from damage.
Check the waveform of the applied voltage while testing. High
voltage due to distortions of the applied voltage may be produced
depending on the type of testing equipment.

Insulation Test
When performing the test, be sure to short-circuit all the output
terminals to protect them from damage.
Inrush Current
When two or more Power Supplies are connected to the same input,
inrush current is added to the total current. Select fuses and circuit
breakers giving sufficient consideration to the fusing or operating
characteristics so that fuses will not burn and breakers will not break
due to inrush current.
Output Voltage Adjuster (V.ADJ)
Default Setting: Set at the rated voltage
Adjustable Range: Adjustable with output voltage adjuster (V.ADJ) on
the front panel of the Power Supply from −20% to 20% of the rated
output voltage (−10% to 20% of the rated voltage for S8VM-
@@@24A@/P@). Turning clockwise increases the output voltage and
turning counterclockwise decreases the output voltage.
The output voltage adjuster (V.ADJ) may possibly be damaged if it is
turned with unnecessary force. Do not turn the adjuster with
excessive force.
After completing output voltage adjustment, be sure that the output
capacity or output current does not exceed the rated output capacity
or rated output current.
The output voltage may increase beyond the allowable voltage range
(up to +20% of the rated voltage) depending on the operation of the
output voltage adjuster (V.ADJ). When adjusting the output voltage,
check the output voltage of the Power Supply and be sure that the
load is not damaged.
When increasing the output voltage to more than +20% of the rated
value using the output voltage adjuster (V. ADJ), the overvoltage
protection function may operate.
(S8VM-@@@24A@/P@ Only)
Turn the output voltage adjuster (V.ADJ) slowly. When decreasing the
output voltage quickly, or when adjusting the output voltage to less
than −10% of the rated value, the undervoltage alarm function may

(S8VM-15224C Only)
The rated ripple noise voltage was measured using a measuring cir-
cuit that conforms to the JEITA standard RC-9131A.
Dielectric Strength
When testing the dielectric strength, some testing devices will apply
a much higher voltage than expected. Always check the applied
waveform before testing the dielectric strength.
Remote Sensing Function
100/150-W Models
If the +S and −S terminals are opened by removing the short bar, the
overvoltage protection function will be activated and the output volt-
age will be cut off.
300/600/1,500-W Models
The stability and accuracy of the output will deteriorate if the +S and
− S pins are open. Always connect the +S and −S pins.
Series Operation
Two Power Supplies can be connected in series.
The (±) voltage output can be accomplished with two Power Sup-
plies.
Series Operation
Note: 1. If the load is short-circuited, a reverse voltage may be ap-
plied inside the Power Supply unit, and this may possibly
cause the deterioration or damage of the Power Supply unit.
Connect the diode as shown in the figures. Use the following
guidelines to select the diode to be connected.
2. Though Power Supplies having different specifications can
be connected in series, the current flowing through the load
must not exceed the smaller rated output current.
Parallel Operation
15/30/50/100/150-W Models
The Power Supply is not designed for parallel operation.

300/600/1,500-W Models
If the CB pin (pin 5 on CN) and the CBG pin (pin 6 on CN) are con-
nected, the current balance function will operate and parallel opera-
tion will be possible at 80% or less of the total output capacity.
Up to 2 Power Supplies can be connected.
Use 2-conductor shielded cable as connection wire (* 1).
Adjust the output voltage of each Power Supply to the same value
within 1% of the rated voltage or so that the difference in the output
voltage is 100 mV or less, whichever is smaller, using the output volt-
age adjuster (V. ADJ).
Parallel operation is used to increase static capacity. The output volt-
age may drop with sudden load fluctuations.
There may be steps in the rising waveform of the output voltage dur-
ing parallel operation.
Remove the standard supplied connector and prepare a connector
harness separately.
In Case There Is No Output Voltage
15/30/50/100/150-W Models
The possible cause for no output voltage may be that the overload
protection or overvoltage protection has operated. The internal pro-
tection circuit may operate if a large amount of surge voltage such as
a lightening surge is applied to the input.
If there is no output voltage even after checking the following points
please contact your OMRON representative.
Check the overload protected status.
Check whether the load is in overload status or is short-circuited.
Remove the load wires when checking.
Attempt to clear the overvoltage or internal protection
function.
Turn OFF the input power once and leave it OFF for at least 3 min-
utes. Then turn it ON again to see if this clears the condition.
Check whether the +S terminal and −S terminal are open, i.e., if the
short bar has been removed. (S8VM-100@@@@/S8VM-150@@@@
only)
Check if the output voltage has been adjusted to more than +20% of
the rated voltage using the output voltage adjuster (V. ADJ).
300/600/1,500-W Models
The possible cause for no output voltage may be that the overcurrent
protection, overvoltage protection, or overheat protection has oper-
ated. Alternatively, the built-in fan may have stopped or the remote
control function may be OFF.
If there is no output voltage even after checking the following five
points, please contact your OMRON representative.
Check the overload protected status.
Check whether the load is in overload status or is short-circuited.
Remove the load wires when checking.
Attempt to clear the overvoltage protection function.
Turn OFF the input power once and leave it OFF for at least 3 min-
utes. Then turn it ON again to see if this clears the condition.
Check whether the +S terminal and −S terminal are open.
Check if the output voltage has been adjusted to more than +20% of
the rated voltage using the output voltage adjuster (V. ADJ).
Check the overheat protected status.
Turn OFF the input power and leave it OFF until the Power Supply
cools sufficiently. Turn it ON again to see if this clears the condition.
Check if the built-in fan motor has stopped.
Check if the built-in fan motor has stopped. The fan is a consumable
part.
Check the remote control function.
Check if the +RC and -RC pins are open. Make the correct connec-
tions as specified.
Fan Replacement
300/600/1,500-W Models
Consult with OMRON regarding fan replacement. OMRON will
replace fans for a fee. A replacement Fan Unit (S82Y-VM@@FAN) is
available. Use the curve in the graph below as a rough measure of
replacement timing.
The Power Supply will not conform to safety standards if the cus-
tomer replaces the fan.
Buzzing Noise when the Input Is
Turned ON
50/100/150/300/600/1,500-W Models
A harmonic current suppression circuit is built into the input power.
This circuit can create noise when the input is turned ON, but it will
last only until internal operation stabilizes and does not indicate any
problem in the Power Supply.
DIN Rail Mounting
15/30/50/100/150/300/600-W Models
When mounting to a DIN Rail, lower the
S8VM onto the Rail until the Rail stopper
clicks into place, hook section A over the
edge of the Rail and push in the direction of
B.
To remove the S8VM from the DIN
Rail, insert a screwdriver into section
C and pull the S8VM away from the
Rail.
