Operation at no load will not damage the units, however, they may not meet all specifications. 3. Load regulation is measured for an output change of 10% to 100% at nominal input line. 4. All units are rated for EN 55022 (CE/RE) class B without external components. 5. 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 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-xxEPB series, a 3.15A/250 VAC slow blow should be used. The diagram below illustrates a typical application connection of the MPM-20EPB 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 filtering capacitors are: C1 1.0 µF/50V 1.0 µF/50V 1.0 µF/50V 1.0 µF/50V 1.0 µF/50V MPM-20S-03EPB MPM-20S-05EPB MPM-20S-12EPB MPM-20S-15EPB MPM-20S-24EPB C2 220 µF/10V 220 µF/10V 120 µF/25V 120 µF/25V 68 µF/35V TVS SMBJ7.0A SMBJ7.0A SMBJ20A SMBJ20A SMBJ30A The output filtering capacitor (C2) is a high frequency, low resistance electrolytic 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-20S-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.
