Typical Connection

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

to achieve a specific output.

4. Recommended output filtering capacitors are:

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.

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.

Input Voltage Vs Load

The diagram below illustrates a typical application connection of the MPM-20S-xx series. Notes on this circuit (starting with the input circuit) are:

The MPM-20-xx series is also available with

a chassis mount or DIN mount adapter.
