14-1-2 Circuit description Control

(a) AC Power Rectification/Smoothing Terminal

1) BD01 : Convert AC power to DC (Wave rectification).
2) CIS01 : Smooth the voltage converted to DC.
3) L1S02, C1S04, C1S05 : Noise removal at power input/output.
4) R1S04 : Rush current limit resistance at the momemt of power cord insertion.

· Without R1S04, the bridge diode might be damaged as the rush current increases.

(b) SNUBBER Circuit : R1S02, R1S03, C1S08, C1S07, D1S05
