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 561KD20 or equivalent is recommended.

3. Recommended output filtering capacitors are:

4. Input noise and surge suppression modules are available for a number of MPD

AC/DC power supplies. An MPM-12S-xxEPB connection with the ACFM-02

is illustrated 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 (±4 kV) and EN 61000-4-5 (±2 kV) without

external components. They will meet EN 61000-4-5 (±4 kV/ ±6 kV) with ad-

ditional input filtering as shown below.

5. It is recommended that a fuse be used on the input of a power supply for

protection. For the MPM-12S-xxEPB 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-12EPB series. Notes on this circuit (starting with the input circuit) are:

The MPM-20-xxEPB series is also available with

a chassis mount or DIN mount adapter.
