Notes:

1. Load regulation is measured for an output change of 10%

to 90% at nominal input line. For multiple output models,

the loads are balanced.

2. It is recommended that a fuse be used on the input of

a power supply for protection. For the MPM-05 series, a

1A/250 VAC slow blow should be used.

Typical Connection

The diagram above illustrates a typical application connection of

the MPM-03 series. Notes on this circuit (starting with the input

circuit) are:

1. To maintain clearance and creepage distances (for Class I & Class II

devices) the board layout should guarentee the following spacing

between the L and N inputs (before the fuse):

Clearance - 2 mm

Creepage - 2.5 mm

2. The recommended fuse is a 1A/250V slow blow. A 10Ω/2W wire

wound resistor may also be used.

3. For EMI sensitive applications, the input filtering circuit (inside the

dotted boxes) may be added. The filter consists of:

C

C

T

about 10 mH & wire diameter of 0.22 mm.

4. The MOV is added for protection. Recommended is a 471KD07.

5. The input filtering capacitor (C

capacitor can be removed if the application input is between 160

to 264 VAC.

6. The output filtering capacitor (C

tance electrolytic capacitor.

7. The TVS is recommended to protect application circuitry in the

event of a fault.
