Typical application circuit

APPLICATION CIRCUIT

Input part

Fuse/fuse: protection circuit when the module is abnormal(Recommended: 0.5A/250Vac slow blow)

Varistor/ Varistor: Protection module when accumulated surge(Recommended:10D561K)

C1/Safety capacitor: filter, safety protection (EMC certification)(Recommended:0.1uF/275Vac)

L1/Common mode inductor: EMI filtering(Recommended: inductance 10-15mH, current 70-500mA)

*Fuse and varistor are basic protection circuits (required)

*If certification is required, safety capacitors and common mode inductors cannot be omitted

Output section

C2/filter capacitor

Filtering, after adding this capacitor, the output ripple can be controlled within 30mV.

[Recommended] Aluminum electrolytic capacitors, with a capacitance value of 100-220uF, and withstand voltage derating greater than 75%.

RL/load

load

*The C2 filter capacitor can reduce the output ripple from the original 50mV to within 30mV.
