Suggestion typically application ( can promote the EMI/EMC )


l        Input filter parts:

1. if the products used for the high EMC occasions, where have to add “EMC filter”, C4: advise 0.33uF/2000VDC or higher capacitance value, NF: common mode choke  advise 30MH

2. MOV voltage dependent resistor, Model: 152KD14need two in series connection. you can connect by real situation to protect power module when lighting stroke the surge. Fuse have choose he high stand voltage fuses,0.5A-1A.NTC use 5D-9 be available.

l        Input start parts:

RD1 is resistance for 25KΩ,advise watts 10W,

RD2 is resistance for 200KΩ,advise 50W, allow the start time,the resistance can be changes from  200KΩ-3MΩ,the smaller resistance,the faster the start time.
