Circuit Operation Description
1. Input Filtering Circuit
This component is consistsed of the Common Mode Reactors (L8101, L8102), the X-cCondensers (C8101, C8105,
C8109), the Line By pass cCondensers (Y-cCondensers: C8103, C8104, C8107, C8108, C8111, C8112), and the
lLightning aArrestor eElements(NR8101, NR8102, NR8103, SQ8101, SQ8102).
This component reduces the line-conducted external noise and the feedback noise from the power supply.

2. Rectifier Circuit
This component converts the inputincoming AC power into DC power.
[Power Circuit]
- Aux. Power Circuit
D8131 doesperforms the half-wave rectification on the AC input and C8131 produces DC voltage with less ripple.
-Main pPower cCircuit
The Rrectified AC input is converted into DC output voltage.
