85-264Vac or 110-340Vdc

Universal Input

DMS-PS-CM Series

DATEL’s DMS-PS-CM Series of high-efﬁ ciency, chassis mount AC/DC power sup-

plies feature low noise (40mV on main, 8mV on auxiliaries), fully-isolated +24, +12V,

and +5V outputs, making them perfect for powering today’s complex instrumentation.

A high-current main output is isolated from the AC line by 3000Vac. In dual- and triple-

output models, the low-current auxiliary outputs are isolated from the main output by

1000Vdc, and from each other by 2000Vdc, effectively providing double isolation from

the A C line! This unprecedented isolation eliminates ground loop problems in complex,

multiple-instrument applications.

Full-load efﬁ ciencies of up to 80% and output-power ratings of 5, 10 or 16

Watts, combine to ensure minimal ac power consumption. For intermittent use or low-

power applications, the 5-Watt model’s no-load quiescent consumption with a nominal

120Vac input is a mere 0.6 Watts---that’s nearly seven times less than a standard

4W night light! These low cost, high-efﬁ ciency power supplies can signiﬁ cantly reduce

long-term electricity costs in low (<5Watts) to medium (<16Watts) power applications.

All DMS-PSX-CM power supplies feature universal inputs of 85-264Vac 50/60Hz,

built-in line fuses, and on-board ‘Power On’ LED indicators. At full rated load, hold-up

time is typically 20ms at 120Vac, and 80ms at 230Vac. All outputs provide indeﬁ nite

short-circuit protection and, for added reliability, the main high-current output also

includes overvoltage protection. A rugged, vibration-proof, chassis mount package

incorporates large, shock-resistant terminal blocks for all I/O connections.

Multiple outputs, low noise, low cost, high efﬁ ciency, double isolation, and rugged

construction combine to make DMS-PSX-CM Series AC/DC power supplies the ideal

choice for powering today’s sensitive instrumentation, and any electronic device that

requires a reliable dc voltage!

1. Shock Hazard: DMS-PS-CM Series power supplies feature touch-

proof terminals blocks and fully-isolated plastic construction, thereby

greatly reducing the risk of electrical shock. However, these are mains-

powered devices whose operation is derived from hazardous and

potentially lethal voltages.

All service and installation must be performed by qualiﬁ ed personnel,

with the ac supply voltage de-energized. Before making connections to

any of the unit’s terminal blocks, use a digital voltmeter to verify that the

ac supply is de-energized (off).

2. AC Supply Fuse (F1): All DMS-PS-CM Series power supplies are

equipped with a built-in 1A/250V time-lag fuse. Replacement fuses

must be of the same type and rating; please refer to the Functional

Speciﬁ cations section of this datasheet for more information. F1 is

conservatively rated in order to reduce nuisance tripping which might

occur during power-up or output overload conditions. However, F1 is

primarily intended to provide protection in the event of catastrophic

failure in the DMS-PS-CM’s ac/dc converter.

IMPORTANT! To ensure safe and reliable operation, DMS-PS-CM

power supplies must be installed and serviced by qualiﬁ ed per-

sonnel. Contact DATEL if there is any doubt regarding their instal-

lation and/or operation. Please read all of the following technical

and application notes BEFORE installing or making connections

to DMS-PS-CM power supplies.

3. Fuse Replacement: If any dc-output drops to zero volts, and no fault

conditions exist within the external load circuitry or the ac mains, F1

may have failed. F1 is located on the circuit (etch) side of the pc-board.

Fuse replacement is performed by ﬁ rst de-energizing and then discon-

necting the ac mains from TB4. Next, disconnect all load wiring from

TB1, TB2, and TB3. Lastly, remove the four screws that secure the

pc-board to the plastic case. After making sure that the new fuse is

securely attached to its mounting clips, re-assemble the unit using all

four screws. Reconnect all input and output wiring and re-apply ac

power.

If the unit still does not operate properly, and the ac supply at TB4 is

measured to be within its speciﬁ ed operating range, the power supply

is defective and must be replaced. Except for F1, DMS-PS-CM supplies

contain no other user-serviceable components.

4. Wire Gauges and Fusing: All wiring connected to the DMS-PS-CM’s

terminal blocks must meet the requirements speciﬁ ed in the Functional

Speciﬁ cations section. All ac supply and load wiring must be rated

for the voltages and currents they will conduct and must comply with

any code or application-mandated requirements pertaining to the user’s

speciﬁ c installation. Applications subject to vibration should include

adequate strain reliefs on both input and output wiring. Install the strain

reliefs within 2-3 inches (5-7.5cm) of the terminal blocks.

It is recommended that all wiring be rated for 600V and 105°C opera-

tion (UL1015 type, for example). Also, wire insulation must be stripped

to within ±10% of the dimensions shown in Figure 2. All wires must

be inserted into their respective terminal blocks such that the screw

terminal does not pinch their insulation. No more than two wires

should be connected to any single terminal on TB1 through TB4.

If two wires are attached to a single terminal, be sure to use only two

20AWG (0.5mm2) wires on TB1, TB2, and TB3, and only two 18 or

20AWG (0.75 or 0.5mm2) wires on TB4.

Dangerous, potentially lethal voltages are present during

normal operation. Disconnect ac mains before servicing.

Reference document: IEC 417, No. 5036.

Caution, refer to accompanying documents for more information.

Reference document: ISO 3864, No. B.3.1.

Caution, unit may become hot in normal operation, thereby creat-

ing a potential burn hazard. Disconnect ac mains and then allow

unit to cool before servicing.

Reference document: IEC 417, No. 5041.

DATEL, Inc., Mansﬁ eld, MA 02048 (USA) • Tel: (508)339-3000, (800)233-2765 Fax: (508)339-6356 • E–mail: sales@datel.com • Internet: www.datel.com

The ac-mains circuit supplying power to DMS-PS-CM supplies must

be fused according to the current rating of the wire gauge used, in

accordance with applicable regulatory codes. The built-in 1ampere line

fuse (F1) only protects the module itself from destructive over currents.

5. AC Mains Connections (TB4): To ensure EMI-compliant operation,

all three ac-supply inputs must be properly connected to TB4. Never

operate any DMS-PS-CM power supply without a ground connection

to TB4’s ‘FG’ terminal.

On 120Vac 50/60Hz mains, connect the black or "hot" lead to ‘AC(L)’,

the white or “neutral” lead to ‘AC(N)’, and the supply ground (earth)

to ‘FG’ (Frame Ground). On 220V 50/60Hz ac mains with line and

neutral conductor-designations, connect the line to AC(L), the neutral

to AC(N), and the ground to ‘FG’.

6. Connector Torque Ratings: It is extremely important to tighten all

input and output terminal blocks securely. TB4’s screw terminals must

be torqued to 4.4 pound-inches (0.5Nm). TB1, TB2, and TB3 must be

torqued to 3.6 pound-inches (0.4Nm). Proper tightening will minimize

losses and ensure safe, reliable operation.

7. ‘Power On’ LED: The Power On LED indicates that the unit has

ac-power applied and its V1 dc-output is operational. However, the

power-on LED’s illumination does not imply nor guarantee that the

unit’s dc-outputs are within their speciﬁ ed accuracy.

8. Output Adjustment: The main output, V1, on all 5, 10, and 16W

models is adjustable by approximately –10% to +15%. V1’s adjustment

potentiometer is accessed via a small hole located next to the

Power-On LED. While not recommended, ﬁ eld adjustment of single-

output models can be performed within the tolerance window noted

above. However, keep in mind that the unit’s maximum output power

capability must not be exceeded. For example, increasing V1’s output

voltage by 10% produces a corresponding 10% reduction in V1’s

maximum output current.

On dual-and triple-output units, V1 is factory calibrated with all

outputs simultaneously loaded to 100% of their rated current. On

all dual- and triple output models, adjusting V1 under any condi-

tion other than those just noted (i.e., all outputs loaded to their

full rated current) will adversely affect the operation and stability

of auxiliary outputs V2 and V3. On these models, V1 must be

adjusted to within ±2 % of its nominal value (+5.0V, +12.0V, or

+24.0V, depending on model).

9. Temperature Derating (See Figure 3): All DMS-PS-CM supplies are

speciﬁ ed to operate at their full rated power over the temp range of 0°C

to +50°C in still air (convection cooling) without any thermal derating.

For operation over +50°C in still air, derate the output power linearly by

2.5% per °C down to 50% rated power at +70°C. To operate the units at

full rated power between +50°C and +70°C, a minimum forced-airﬂ ow

of 100 LFM is required. For operation below 0°C, derate the output

power linearly by 2.0% per °C down to 50% rated power at –25°C.

Unless forced air with the velocity noted above is employed, DMS-

PS-CM supplies should never be mounted upside down (terminal

blocks facing down). Also, always provide sufﬁ cient clearances in order

to ensure adequate airﬂ ow around the supply.

10. V1 Peak Capabilities: DMS-PS-CM power supplies have a maximum

continuous output-current rating that’s speciﬁ ed in the Ordering and

Selection Guide. In addition, each model’s V1 output can intermittently

supply 120% of its continuous rated current for short periods of time if

the duty cycle is less than 10%. Peak current ratings do not apply to

the auxiliary outputs V2 or V3.

11. Isolated Outputs: Unlike the majority of competitive ac/dc power sup-

plies, all dual- and triple-output DMS-PS-CM power supplies feature

fully-isolated outputs. This is an important feature when, for reasons

of high common mode voltages, an instrument’s input circuit must be

isolated from the system ground. All V1 outputs are isolated from the ac

mains by a minimum of 3000Vac, while auxiliary outputs V2 and V3 are

isolated from one another by 2000Vdc, and fromV1 by 1000Vdc. The

low noise, double-isolated auxiliaries are ideal for powering sensitive

instrumentation that requires low ac leakage-currents.

All ac/dc and dc/dc power components utilized in the construction

of DMS-PS-CM power supplies are 100% hi-pot tested during their

manufacturing processes. In addition, after ﬁ nal assembly by DATEL,

all models are subjected to an additional hi-pot testing consisting of

3. Model Selection & Energy Conservation: In order to achieve the

lowest possible energy consumption, be sure to determine your appli-

cation’s total current requirements. This is especially true when using

DMS-PS-CM supplies to power DATEL’s energy-efﬁ cient LED and/or

LCD display digital panel meters (DPMs) and process monitors. In

general, choose a power supply that will accommodate your maximum

current consumption plus a 20% margin. Choosing the lowest-wattage

model suitable for a given application will provide lower procurement

costs and lower long-term operating costs.

When calculating total current requirements in installations employing

three or more DMS-Series meters, it is acceptable practice to use each

meter’s typical current consumption rating. However, be sure to consult

the relevant product datasheets for all instrumentation comprising your

application.

For applications where DMS-PS-CM power supplies will be powering

only DATEL DPM’s, a 5-Watt DMS-PS3-CM can power up to four, stan-

dard intensity (‘-RS’ sufﬁ x) red-LED DMS-30PC meters: two meters on

V1, and one meter each on V2 and V3. The same DMS-PS3-CM could

also be used to power over 40 low-power red DMS-30PC meters (‘-RL’

sufﬁ x), or over 800 DMS-30LCD non-backlit meters! Of course, these

statements are made without regard to ground-loop problems that may

be encountered when powering 800 DPM’s from a single power supply.

1000Vac sequentially applied between the ac mains input and each

output, and between each output and all other outputs.

Application Information

1. Chassis Mounting Considerations: In order to minimize self-heating,

DMS-PS-CM power supplies should always be mounted in either a

vertical or horizontal position. Avoid mounting units upside-down or in

close proximity to other heat-generating devices. Also, be sure to use

the mounting hardware described in Figure 4 below in order to ensure

a secure, vibration-resistant installation.

Figure 4. Chassis Mounting

2. Bipolar Operation (See Figure 5): DMS-PS-CM power supplies’ fully

isolated outputs allow for the generation of bipolar (positive and nega-

tive) supply voltages. Bipolar outputs can be used to power dual-supply

operational ampliﬁ ers, as well as any other type of instrumentation that

requires bipolar supply voltages. However, please keep in mind that

when connecting and operating any two outputs in this fashion, each

output retains its maximum current rating.
