Note:
C1:AC input, C1is input filer capacitor (which is required);
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).
C2 and C3 are output filer capacitors (which is required), C2,C3 and L1 form a pi-type filter circuit, 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% or above. C4 is a ceramic capacitor, which is used to filter high frequency noise. Current of L1 and L2 refer to the
datasheets provided by the manufactures, current derating should be 80% or above. TVS is a recommended component to protect post-circuits (if converter
fails). External input NTC model is recommended to use13D-5. External input MOV model is recommended to use S14K320.
