Typical Connection

1. It is recommended that an external fuse and NTC be used.The recommended

fuse is a 0.5A/250V slow blow and for the NTC, a 5D-9.

2. An external MOV is recommended on the input to protect the unit in the event

of a surge. A 561KD14 or equivalent is recommended.

3. Recommended output filtering capacitors are:

The output filtering capacitor (C

2

) is a high frequency,low resistance electrolytic

capacitor. Capacitor (C

1

) 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-03S connection with the ACFM-01 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. For the 3.3V output model, Output Accuracy is ±3.0%

2. 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 A without external components.

They will meet EN 55022 class B with the addition of the ACFM-01 (or a

similar discrete filter circuit). Contact the factory for more information.

5. To meet the input surge requirements of EN 61000-4-4 (±2 kV) & EN 61000-4-5

(±1 kV /±2 kV), external components are needed. This can be done discretely,

or with the addition of the ACFM-01. Contact the factory for more information.

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

protection. For the MPM-03S series, a 0.5A/250 VAC slow blow should

be used.
