Variable power cooking control
The coil of power relay A and B are energized intermittently by
the digital programmer circuit, when the oven is set to MEDIUM
or DEFROST power position. The digital programmer circuit
controls the ON-OFF time of the power relay A and B contacts
in order to vary the output power of the microwave oven. One
complete ON and OFF cycle of the power relay is 44 seconds.
The relation between indications on the control panel and the
output power of the microwave oven is as shown in Figure.
