1. OUTLINE
The part that supply DC VOLTAGE to each circuit change AC input voltage into DC voltage. It is based on
SMPS(switching mode power supply)system which is located on main PCB. SMPS module is composed of the
switching circuit and the transformer of the primary part and the rectifier circuit of the secondary part.
