Overview
The AC Power assy's main tasks are to supply powers the various internal subsystems and to isolate
electrically the scanner from the on site Mains Power System. The voltage to peripherals can be
confederated to either 110 VAC or 220 VAC. Internal circuit for AC power have the free voltage
capability basically but, we should separate the group using of low voltage (100V~127V), high voltage
(200V~240V), and mixed voltage (100V~120V for peripheral and 200V ~ 240V for system).

TRANSBOX(AC Power)
The mains cord has plugs in one side end. A male plug connects to the mains outlet on site. The mains
voltage is routed to the Main Circuit Breaker, located on the rear side of the system. The Main Circuit
Breaker is of the auto fuse type, if for some reason the current grows to high, the switch will
automatically break the power. From the Main Circuit Breaker, the AC power is routed via the Mains
Transformer and the Inrush Current Limiter to internal outlet connector for AC distribution.
The Transformer is the galvanic barrier between the rest of the scanner and the on site AC Mains. Input
voltage to the transformer can be either 220 VAC or 110 VAC. AC output of transformer is supplied to
the APS/APS Pro through Inrush Current Limiter without additional control. AC output of transformer for
LCDMON, 4D BOX(option), and peripheral controlled by the L1SYSCON according to the On/Off status
of the system.
