Note!
1. Output filtering capacitors C1, C3 is electrolytic capacitors, It is recommended to use high frequency and low impedance electrolytic capacitors. For
capacitance and current of capacitor please refer to manufacture’s datasheet. Voltage derating of capacitor should be 80% or above. C2, C4 is ceramic
capacitors , it is used to filter high frequency noise. TVS is a recommended component to protect post-circuits (when converter fails).
2. MOV is required for VSK-S3 models. Model: 471KD05, it is used to protect the device under surge.
3. It is recommended to connect FUSE, the parameter is 0.5A/250V slow blow. External input NTC is recommended to use
D -14 or10Ω/2W wire-round resistor.
4. If EMC performance is required, recommended to add“EMC filter” at the input end(see figure 2)
C6:X capacitor, recommended parameter 0.1uF/275V;
C7,C8:Y capacitor, recommended parameter 220pF/2000V;
NF: common model choke, recommended inductance is about 10mH-30mH.
5. Terminals 22 and 26 are internal rectification and filtering terminals. To protect the models further, it is recommended to connect an electrolytic
capacitor C3 (it is recommended to be 4.7uF/400V). If operation voltage of the module is between 160~264VAC, C3 can be removed.
