Overview
The main function of the AC Power assy is to supply powers the various internal subsystems, and to
isolate the scanner electrically from the on site Mains Power System. The voltage to peripherals can be
confederated to either 110 VAC or 220 VAC. To reduce inrush current, an inrush current limiter board
(ACPC II assy) has been included in this box. Internal circuits are separated as: 100~127VAC,
200~240VAC, and 100VAC~120VAC for peripheral and 200V ~ 240V for system.

TRANSBOX(AC Power, AP950)
The main 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 power for APS II is being supplied
from transformer through Inrush Current Limiter without additional control. Other AC powers for
LCDMON, 4D BOX(option), and peripheral are being supplied form transformer by On/Off control.
