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 AC 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 (0.5mm

) wires on TB1, TB2, and TB3, and only two 18 or

20AWG (0.75 or 0.5mm

) 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.

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.
