RTN - Primary Power Module (AC/AC)
5-10-1-1
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 is implemented.
Voltage to peripherals can be configured to either 115 VAC or 230 VAC.
From the Mains Power Input module, the AC power is routed via an Inrush Current Limiter to an internal
outlet connector for the Mains Transformer.

Major Functions of RTN
•
Inrush Current limiter
•
The RTN Primary Power Supply module generates 34.5VAC (+/-2V) as an input voltage for the
Secondary Power Supply module (RTP).
•
The RTN module contains also the isolation transformer for the peripherals (AUX).
(Maximum load: 345VA) see: Basic User Manual, Technical Data/Information
NOTE:
All DC-supply voltages for built in peripherals are generated in RTP-module not inside RTN.
NOTE:
The “Mains voltage indicator” on the RTN primary power supply should be set in accordance to the input
voltage level. This indicator is
NOT
a voltage selection switch!

NOTICE
!! NOTICE:
Connector
C14
(10A type) is installed by default.
Note: If the Mains Voltage is lower than 200V, Connector C20 has to be installed!
NOTICE
!! NOTICE:
The systems mains supply input voltage can be set to: 100V, 115V, 125V, 225V and 250V.
Modifications of voltage settings has to be done by an authorized service person only!
The output voltages may be set to 115VAC or 230VAC (independent from the input voltages).
