Overload Protection
The load and the power supply are automatically protected from
overcurrent damage by this function.
Overload protection is activated if the output current rises above
105% of the rated current.
When the output current returns within the rated range overload
protection is automatically cleared.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during
operation.
2. Internal parts may possibly deteriorate or be 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.
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. If an excessive voltage that
is approximately 130% of the rated voltage or more is output, the
output voltage is shut OFF. Reset the input power by turning it OFF
for at least three minutes and then turning it back ON again.
Note: Do not turn ON the power again until the cause of the
overvoltage has been removed.
Inrush Current, Startup Time, Output Hold Time
Note: Twice the input current or above will flow during the redundant
system.
Therefore, check the fusing characteristics of fuses and
operating characteristics of breakers making sure that the
external fuses will not burn out and the circuit breakers will not
be activated by the inrush current.

Two phases application for Single phase models
For All Single phase Models, S8VK-C
Basically OMRON single phase power supply can be used on two-
phases of a 3–phase-system when some of conditions satisfy like
below.
1. The supplying voltage is below the maximum rated input.
OMRON Power supply allows the input voltage equivalent or less
than 240 VAC+10%.
Please confirm the input voltage between two lines if the input
voltage satisfies this condition before connecting.
2. The external protector is needed on N input line to secure a safety.
N line has no protection of a fuse internally.
An appropriate fuse or circuit breaker should be connected on N
input line like the following.

Wiring
•Connect the ground completely. A protective earthing terminal
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 75-N force to the terminal block when
tightening it.
•Be sure to remove the sheet covering the Product for machining
before power-ON so that it does not interfere with heat dissipation.
•Use the following material for the wires to be connected to the
S8VK-C to prevent smoking or ignition caused by abnormal loads.
Terminals and Wiring
•Strip I/O wires for 8 mm when using a screwless terminal block.
Note: The rated current for output terminals is 10 A per terminal.
Be sure to use multiple terminals simultaneously for current that exceeds the terminal rating.
When applying a current of 10 A or more, use at least two terminals each for the positive and negative wires.
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 cut in half 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 10% to 95%.
•Do not use the Power Supply in areas outside the derating curve
otherwise, internal parts may occasionally deteriorate or be
damaged.
•Use the Power Supply at a humidity of 20% to 90%.
•Do not use the Power Supply in locations subject to direct sunlight.
•Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of Products.

Mounting
•Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Product. Be sure to allow
convection in the atmosphere around devices when mounting. Do
not use in locations where the ambient temperature exceeds the
range of the derating curve.
•When cutting out holes for mounting, make sure that cuttings do
not enter the interior of the Products.
•Improper mounting will interfere with heat dissipation and may
occasionally result in deterioration or damage of internal parts. Use
the Product within the derating curve for the mounting direction that
is used.
•Use a mounting bracket when the Product is mounted facing
horizontally.
•Heat dissipation will be adversely affected. When the Product is
mounted facing horizontally, always place the side with the label
facing upward.
•Operate the Power Supply within a range that is 5°C less than the
values in the derating curve in Engineering Data on page 4 if the
Power Supply is used with an installation spacing of 10 mm min.
(20 mm max.) on the left and right.
Overcurrent Protection
•Internal parts may possibly deteriorate or be damaged if a
short-circuited or overcurrent state continues during operation.
•Internal parts may possibly deteriorate or be 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.
•The DC ON indicator (green) flashes if the overload protection
function operates.
Charging a Battery
If you connect a battery as the load, install overcurrent control and
overvoltage protection circuits.
Output Voltage Adjuster (V.ADJ)
•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.
DIN Rail Mounting
To mount the Block on a DIN Rail, hook portion (A) of the Block onto
the rail and press the Block in direction (B).
To dismount the Block, pull down portion (C) with a flat-blade
screwdriver and pull out the Block.
Series Operation
Two power supplies can be connected in series.
Note: 1. The diode is connected as shown in the figure. If the load is
short-circuited, a reverse voltage will be generated inside
the Power Supply. If this occurs the Power Supply may
possibly deteriorate or be damaged. Always connect a
diode as shown in the figure.
Select a diode having the following ratings.
2. Although Products having different specifications can be
connected in series, the current flowing through the load
must not exceed the smaller rated output current.
Making Positive/Negative Outputs
•The outputs are floating outputs (i.e., the primary circuits and
secondary circuits are separated). You can therefore make
positive and negative outputs by using two Power Supplies.
You can make positive and negative outputs with any of the
models.
If positive and negative outputs are used, connect Power Supplies
of the same model as in the following figure. (Combinations with
different output capacities or output voltages can be made.
However, use the lower of the two maximum rated output currents
as the current to the loads.)

•Depending on the model, internal circuits may be damaged due to
startup failure when the power is turned ON if loads such as a
servomotor or operational amplifier may operate in series.
Therefore, connect bypass diodes (D1, D2) as shown in the
following figure.
If the list of models that support series connection of outputs says
that an external diode is not required, an external diode is also not
required for positive/negative outputs.
•Use the following information as a guide to the diode type, dialectic
strength, and current.
Backup Operation
Backup operation can be performed with S8VK-R.
Refer to the S8VK-R Datasheet for detail.
In Case There Is No Output Voltage
The possible cause for no output voltage may be that the overcurrent
or overvoltage protection has operated. The internal protection may
operate if a large amount of surge voltage such as a lightening surge
occurs while turning ON the power supply.
In case there is no output voltage, please check the following points
before contacting us:
•Checking overload protected status:
Check whether the load is in overload status or is short-circuited.
Remove wires to load when checking.
•Checking overvoltage or internal protection:
Turn the power supply OFF once, and leave it OFF for at least
3 minutes. Then turn it ON again to see if this clears the condition.
Audible Noise at Power ON
(240-W, and 480-W Models)
A harmonic current suppression circuit is built into the Power Supply.
This circuit can create noise when the input is turned ON, but it will
last only until the internal circuits stabilize and does not indicate any
problem in the Product.
•Type: Schottky barrier diode
•Dielectric strength (VRRM): Twice the rated Power Supply output
voltage or higher
•Forward current (IF): Twice the rated Power Supply output
current or higher

Period and Terms of Warranty
Warranty Period
The product warranty is valid for a period of three years from the date of shipment from the factory.
Terms of Warranty
The warranty is valid only for the following operating conditions.
1. Average ambient operating temperature of the product: 40°C max.
2. Average load rate: 80% max.
3. Mounting method: Standard mounting
*The maximum ratings must be within the derating curve.
If the product fails for reasons attributable to OMRON within the above warranty period, OMRON will repair or replace the faulty part of the product
at the place of purchase or the place where the product delivered without charge.
This warranty does not cover the following types of failures.
Recommended Replacement Periods and Periodic Replacement for
Preventive Maintenance
The recommended replacement period for preventive maintenance is greatly influenced by the application environment of the product. As a
guideline, the recommended replacement period is 7 to 10 years.*
To prevent failures or accidents that can be caused by using a product beyond its service live, we recommend that you replace the product as early
as possible within the recommended replacement period.
However, bear in mind that the recommended replacement period is for reference only and does not guarantee the life of the product.
Many electronic components are used in the product and the product depends on the correct operation of these components to achieve the original
product functions and performance.
However, the influence of the ambient temperature on aluminum electrolytic capacitors is large, and the service life is reduced by half for each
10°C rise in temperature (Arrhenius law).
When the capacity reduction life of the electrolytic capacitor is reached, the product failures or accidents may occur.
We therefore recommend that you replace the product periodically to minimize product failures or accidents in advance.
*The recommended replacement period applies under the following conditions: rated input voltage, load rate of 50% max., ambient temperature
of 40°C max., and the standard mounting method. (The fan is excluded for models with fans.)
This product model is designed with a service life of 10 years minimum under the above conditions.
(1) Failures that result from handling or operation of the product under conditions or in environments that are not given in this document and
not given in any other specifications exchanged between OMRON and the customer
(2) Failures that originate in causes other than the delivered product itself
(3) Failures caused by disassembly, modification, or repair of the product by anyone other than OMRON
(4) Failures caused by applications or uses for which the product was not originally intended
(5) Failures caused by factors that could not be anticipated with the scientific or technical knowledge available when the product was shipped
(6) Failures caused by other causes for which OMRON is not responsible, such as natural disasters and other acts of God
This warranty is limited to the individual product that was delivered and does not cover any secondary, subsequent, or related damages.
