Notes:
1. Operation at no load will not damage the units, however, they may not meet
all specifications.
2. Load regulation is measured for an output change of 10% to 100% at nominal
input line.
3. All units are rated for EN 55022 (CE/RE) class B without external components.
4. All units are rated for EN 61000-4-4 (±2 kV) without external components. They
will meet EN 61000-4-4 (±4 kV) with additional input filtering as shown below.
5. All units are rated for EN 61000-4-5 (±1 kV/±2 kV) without external components.
They will meet EN 61000-4-5 (±2 kV/±4 kV) with additional input filtering as shown
below.
6. It is recommended that a fuse be used on the input of a power supply for protection.
For the MPM-20S series, a 3.15A/250 VAC slow blow should be used.
Typical Connection
The diagram below illustrates a typical application connection of the MPM-20S-xx series. Notes on this circuit (starting with the input circuit) are:
1. It is recommended that an external fuse and NTC be used. The recommended
fuse is a 3.15A/250V slow blow and for the NTC, a 5D-9.
2. An external MOV is required on the input to protect the unit in the event of a surge.
A 561KD14 or equivalent is recommended.
3. A simple external circuit may be used to adjust the output ±10%. To adjust the
output DOWN, connect a 5%, 3W resistor between the plus output pin and the
VOUT trim pin. To adjust the output UP, connect a 5%, 3W resistor between the
minus output pin and the VOUT trim. Contact the factory for resistor values needed
to achieve a specific output.
4. Recommended output filtering capacitors are:

Derating Curve
Output capacitor (C2) is a high frequency, low resistance electrolytic capacitor.
Capacitor (C1) is ceramic. Voltage derating of capacitors should be 80% or above.
5. Input noise and surge suppression modules are available for a number of MPD
AC/DC power supplies. An MPM-20S-xx connection with the ACFM-01 is il-
lustrated in the diagram at left. For pricing or full technical information on these
modules (ACFM-01 and ACFM-02) please contact the factory.
