CPN6 - Primary Power Module

5-11-1-1 Mechanical Concept and Overview
The AC Power's main tasks are to supply the various internal subsystems with AC power and to
galvanically isolate the scanner from the on site Mains Power System. To reduce inrush current, an
inrush current limiter as well as an EMI filter is implemented.
Voltage to peripherals can be configured to either 115 VAC or 230 VAC.
The mains cord has plugs on both ends.
A female plug connects to the scanner and a male plug to the mains outlet on site.
The mains voltage is routed via an EMI filter to the Mains Switch, located on the rear of the system.
The Mains Switch is of the auto fuse type, if for some reason the current grows to high, the switch will
automatically break the power.
From the Mains Switch, the AC power is routed via an Inrush Current Limiter to a internal outlet
connector for the Mains Transformer.

Major Functions of CPN6

• Inrush Current limiter
• Power factor correction transformer for Sinus load for the mains voltage
• Power down Circuitry + Standby-Switch
• The CPN6 module generates 57VDC (+/-2V) as an input voltage for the Secondary Power supply
of the GEF module.
• The CPN6 module contains also the isolation transformer for the peripherals.
(Maximum load: 350VA)
NOTE: All DC-supply voltages for built in peripherals are generated in GEF-module not inside CPN6.
NOTE: The system mains supply input voltage can be set to: 110V, 130V, 230V, 240V.
The output voltages may be set to 115V or 230VAC (independent from the input voltages)
