EMC Recommended Circuit

Note:

1.The output filter capacitor C1 is electrolytic capacitors, so it is recommended to use a high-frequency and low-resistance electrolytic capacitor. Please refer to the technical specifications provided by manufacturer to check the capacity and current flow. The capacitor withstand voltage derating over 80%. It is suggest to take 0.1 uF, if C2 remove high frequency noise.

2.TVS tube is recommended to use because it protects the back-end circuit(when the converter is abnormal).
3. NTC is thermistor which model: 5D-9.
4. EMC recommended circuit parameters:
MOV is a varistor which recommended model is 471KD10 and its function is to protect the module from damage during lightning surges.
C7 is X capacitor which recommended 0.1µF/275V;
NF is common mode inductance which 10mH-30mH is recommended.
