 EMC recommended circuit
 Remark: The output filter capacitors C1, C3, and C5 are electrolytic capacitors. It is recommended to use high-frequency and low-resistance electrolytic capacitors. Please refer to the technical specifications provided by each manufacturer for the capacity and current flowing. The capacitor withstand voltage drop rate is greater than 80%. C2, C4, and C6 remove high-frequency noise, it is recommended to take 0.1 F. TVS tubes are recommended for protection of later-stage circuits (in case of module abnormality). NTC thermistor, model: 5D-9. EMC recommended circuit parameters:
The MOV is a varistor, the recommended model is: 471KD10, which acts to protect the module from damage during lightning surges.
C7 is an X capacitor, 0.1µF/275V is recommended;
NF is a common mode inductor, 10mH-30mH is recommended. |
