Notes:
1. C1 and C3 are electrolytic capacitors. They are required for both AC input and DC input,
When AC input, C1 is used as filter capacitor, the value of C1 is recommended to be 10µF/400V. When DC input, C1 is used as EMC filter capacitor, the
value of C1 is recommended to be 10µF/400V (when the input voltage is above 370VDC, the recommended value of C1 is 10µF/450V). C2 and C3 are
output filer capacitors, they are recommended to be high frequency and low impedance electrolytic capacitors. Capacitance and rated ripple current of
capacitors refer to the datasheets provided. Voltage derating of capacitors should be 80% or 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 the datasheets provided by the manufacturers, current
derating should be 80% or above. TVS is a recommended component to protect post-circuits (if converter fails). External input NTC is recommended to
use 5D-9. External input MOV1 is recommended to use S14K350.
