Technical description
The switching power supply converts an unstabilized input voltage to a stabilized
output voltage. It provides a constant DC voltage of 12.7 V for DC consumer units.
For power supply, a battery can be connected to the switching power supply via the
battery input (chapter “Connecting the switching power supply” on page 19).
The integrated priority circuit automatically switches over from battery operation to
mains operation when an external power supply is available. The battery is automat-
ically disconnected from the consumer unit.
Battery operation is activated automatically if mains operation is deactivated. The
consumer units connected are supplied with energy via the battery.
