AC Input and EMI Filter:(fig.9)
1)
CN101 is a connector for connecting AC Power. F101&F102 are fuse to protect all the circuit
AC. Input voltage is single 120V. CY101, CY102, CY103, CY104, CY105, CY106 are used high
frequency noise of primary between common GND.LX101,LX102,CX101, CX102 is used to filter
low frequency noise. RX101, RX102 and RX103 are used to discharge CX101 and CX102
remnants voltage
