CPN80 - Primary Power Module

5-11-2-1

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 is implemented.
Voltage to peripherals can be configured to either 115 VAC or 230 VAC.
The mains cord has plugs in both ends. A female plug connects to the scanner and a male plug to the
mains outlet on site.
From the Mains Power Input module, the AC power is routed via an Inrush Current Limiter to a internal
outlet connector for the Mains Transformer.

Major Functions of CPN80

• Inrush Current limiter
• Power factor correction transformer for Sinus load for the mains voltage
• Power down Circuitry + Standby-Switch
• The CPN module generates 57VDC (+/-2V) as an input voltage for the Secondary Power supply of
the GEF module.
• The CPN80 module contains also the isolation transformer for the peripherals.
(Maximum load: 350VA) see: Basic User Manual Chapter 23 Technical Data/Information
NOTE: All DC-supply voltages for built in peripherals are generated in GEF-module not inside CPN80.
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).
