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 specified 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, field 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
specified 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-airflow
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 sufficient clearances in order
to ensure adequate airflow around the supply.
10.V1 Peak Capabilities:
DMS-PS-CM power supplies have a maximum
continuous output-current rating that’s specified 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 final assembly by DATEL,
all models are subjected to an additional hi-pot testing consisting of
