Note:
1. C1: AC input, is filtering electrolytic capacitor (which is required), and the value of C1 is 22μF/400V.
DC input, is a filtering capacitor in EMC Filter, the value of C1 is 10μF/400V(when input voltage is above 370VDC, and the value of C1 is 10μF/450V), If EMC
performance is not required,C1 could not need.
2. C2 and C3 are output filer capacitors(which is required), they are recommended to be high frequency and low impedance electrolytic capacitors
Capacitance and rated ripple current of capacitors refer to the datasheets provided by the manufactures. Voltage derating of capacitors should be 80% o
above. C4 is a ceramic capacitor, which is used to filter high frequency noise. C2, C3 and L1 form a pi-type filter circuit. Current of L1 and L2 refer to th
datasheets provided by the manufactures, current derating should be 80% or above. TVS is a recommended component to protect post-circuits (if converte
fails). External input NTC is recommended to use 5D-9.External input MOV1 is recommended to use S14K350.
