    DESCRIPTION OF MAIN CIRCUIT OPERATION RAK-35RPC,RAK-50RPC 1. Control power circuit Switching power circuit Fig. 1-1 ・ An AC power supply from outdoor unit passes through the 3.15 A fuse, varistor (VA001), and noise filter circuit and rectified and smoothed by DB1 and C003 to become a DC current 325 V. It is then supplied to indoor fan motor drive circuit,and switching power circuit.
