Overview
The AC Power assy’s main tasks are to supply the various internal subsystems and to galvanically
isolate the scanner from the on site Mains Power System and to control power on/off. The voltage to
peripherals can be confederated to either 110 VAC or 220 VAC.

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 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 an Inrush Current Limiter to a internal outlet
connector for the Mains Transformer.
