7-2 PCB FUNCTION
7-2-1 POWER CIRCUIT
The second part of the Transformer is composed of the power supply for the
display and relay drive (12 Vdc) and for the MICOM and IC (5 Vdc).
The voltage for each part is as follows:
VA1 prevents overvoltage and noise. When 175 V or higher power is a pplied, the
inside elements are short-circuited and broken, resulting in the blowout of the fuse
in order to protect the elements of the secondary part of the Transformer.
