7.1 Variable cooking power control
The HIGH VOLTAGE INVERTER POWER SUPPLY controls the output power by a signal from the Digital
Programmer Circuit (DPC). The Power Relay (RY1) turns on to supply power to the inverter circuit. The level
of output power is controlled by the drivesignal level from the inverter circuit as indicated in the table below.
NOTE 1: The ON/OFF time ratio does not correspond with the percentage of microwave power since
approximately 2 seconds are required for heating the magnetron filament.
NOTE 2: If microwave cooking is over 8 minutes on HIGH power, the fan motor rotates for 1 minute after
cooking to cool the oven and its electrical components.
