Note:
1. Output filtering capacitor C2 is an electrolytic capacitor. It is recommended to use high frequency and low impedance electrolytic capacitors. For
capacitance and current of capacitor please refer to the manufacturer’s datasheet. Voltage derating of capacitor should be 80% or above. C1 is a ceramic capacitor that
is used to filter high frequency noise. External input NTC is recommended to use 5D-9
2. The fuse is internally included, it does not need to be added to the circuit.
