Note

1. Output filtering capacitors C1, C3 is electrolytic capacitors, It is recommended to use high frequency and

low impedance electrolytic capacitors. For capacitance and current of capacitor please refer to manufacture’s

datasheet. Voltage derating of capacitor should be 80% or above. C2 is ceramic capacitor, it is used to filter

high frequency noise. TVS is a recommended component to protect post-circuits (when converter fails).

2. MOV is required to PPM03 models, model: 471KD05, it is used to protect the device under surge.

3. It is recommended to connect FUSE, the parameter for PPM03 models is 0.5A/250V slow blow. External

input NTC is recommended to use 5D-14 or 10 /2W wire-round resistor.

4. If EMC performance is required, recommended to add “EMC filter” at the input end C6:X capacitor,

recommended parameter 0.1uF/275V; C7,C8:Y capacitor, recommended parameter 220pF/2000V;

NF: common model choke, recommended inductance is about 10mH-30mH.

5. PPM03 models: Terminals 22 and 26 are internal rectification and filtering terminals. To protect the models

further, it is recommended to connect an electrolytic capacitor C3 (it is recommended to be 4.7uF/400V). If

operation voltage of the module is between 160~264VAC, C3 can be removed.

Specification can be changed without notice.
