3072 power supply

The3072 power supply is an AC adaptor (220V/50Hz), which supplies a stabilized voltage of 13,6V with a load of up to 8A. This power supply can be combined with a 12V battery. In the event of voltage decay or an excessive voltage drop, the power supply compensates by discharging the battery and automatically switches over onto the backup supply.

 It is produced as a pulse constant-voltage regulator system with a separate transformer. This power supply is destined to supply radiotelephones with voltage ratings equal to 12V.
