5.9.1.1 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 system from the on site Mains Power System. To reduce inrush current, an inrush current limiter
is implemented.
From the input voltage from the Power Supply (RSP) the AC/DC device generates all system supply
voltages, which are:
•
FrontEnd voltages
•
Standby voltages
•
ATX motherboard supply
•
Tx voltages
In addition the AC/DC device contains the digital motor amplifier.
5.9.1.2 Input Voltage Range
input voltage range: 100 - 240VAC; 50/60Hz
5.9.1.3 Auxiliary Output Voltage
nominal 115VAC
All DC-supply voltages for built-in peripherals are generated in the RSP- Power Supply Module.
