Main Power Supply Assembly

The main power supply comprises a closed assembly (no on-site 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 – 240 volts AC ± 10% and needs no manual setting.

No accessible hardware fuse is needed because the main power supply is safe
against any short circuits or overload conditions on the output lines. When
overload conditions occur, the power supply turns off all output voltages.
Turning the line power off and on again resets the power supply to normal
operation if the cause of the overload condition has been removed.
