7-2 PCB FUNCTION
7-2-1 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), 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 high voltage 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.
