8-2 PCB FUNCTION
8-2-1 Power Circuit
The secondary part of the TRANSFORMER is composed of the power supply for the display, the BLDC FAN Motor drive
(15.5 V dc), the relay drive (12 Vdc) and the MICOM and IC (5 Vdc).
The voltage for each part is as follows:
VA1 is a part for preventing over voltage and noise. When 385V or higher power is applied, the inside elements are short-
circuited and broken, resulting in blowout of the fuse in order to protect the elements of the secondary part of the
TRANSFORMER.
