Murata Power Solution’s DMS-PS-CM Series
of high-efficiency, chassis mount AC/DC
power supplies 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
AC line! This unprecedented isolation elimi­nates ground loop problems in complex,
multiple-instrument applications.

Full-load efficiencies 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-efficiency
power supplies can significantly 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 indefinite
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 efficiency, double isolation, and rugged
construction combine to make DMS-PSX­CM Series AC/DC power supplies the
ideal choice for powering today’s sensitive
instrumentation, and any electronic device
that requires a reliable dc voltage!

TECHNICAL NOTES

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

power supplies must be installed and serviced by qualified

personnel. Contact Murata Power Solutions if there is any doubt

regarding their installation and/or operation. Please read all of the

following technical and application notes BEFORE installing or

making connections to DMS-PS-CM power supplies.

Warnings (Marking)

Caution, unit may become hot in normal operation, thereby creat­ing a potential burn hazard. Disconnect ac mains and then allow
unit to cool before servicing.
Reference document: IEC 417, No. 5041.

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.

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

terminals blocks and fully-isolated plastic construction, thereby greatly reduc-

ing 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 qualified 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 Specifications 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.

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 first de-energizing and then disconnecting

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 specified 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 specified in the Functional

Specifications 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 specific

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 operation

(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 (0.5mm

TB2, and TB3, and only two 18 or 20AWG (0.75 or 0.5mm

0.25"

(6.4mm)
