6 Introduction to the Detector

The Main Power Supply Assembly

The main power supply comprises a closed assembly (no onsite repair
possibility).
The power supply provides all DC voltages used in the module except for the
voltages supplied by the lamp power supply to the deuterium and tungsten
lamps in the detectors. The line voltage can vary in a range from 100 – 120 or
220 – 240 volts AC ± 10 % and needs no manual setting.
