Typical Connection The diagram below illustrates a typical application connection of the MPM-12EPB 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 561KD20 or equivalent is recommended.
3. Recommended output fi ltering capacitors are:
MPM-12S-03EPB 1.0 µF/50V 220 µF/10V SMBJ7.0A
MPM-12S-05EPB 1.0 µF/50V 220 µF/10V SMBJ7.0A
MPM-12S-12EPB 1.0 µF/50V 120 µF/25V SMBJ20A
MPM-12S-15EPB 1.0 µF/50V 120 µF/25V SMBJ20A
MPM-12S-24EPB 1.0 µF/50V 68 µF/35V SMBJ30A

The output fi ltering capacitor (C2) is a high frequency, low resistance electrolytic
Typical Connection: With ACFM-02 Input Module (See note 4) capacitor. Capacitor (C1) is ceramic. Voltage derating of capacitors should be
80% or above.
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.
