DESCRIPTIO N
DC Power Supply in circuit needs +12V and +5V. +12V is used for Compressor Driving Relay, Fan Motor
Driving Relay, Buzzer Driving, Swing Motor Driving Relay and LED Display. AC voltage of secondary Power
Transformer is rectified by 4 Diode, and it is filtering by Main Condensor C2.
Filtered DC voltage is about +17V is regulated +12V DC by Regulator IC7812.
And it is regulated +5V DC by Regulator IC7805.
VAR1 is surge filter and C4, C6 is Noise filter.
