1. Technical description.
1.1. General description.
The power supply unit is intended for supplying power to alarm system devices requiring 12 V DC supply voltage
and current load of
I=7 A
. The design enables simple change of the output voltage, within the range of 12 V - 15 V DC, by
means of a potentiometer. The power supply unit is protected against short-circuit, overload and overvoltage.
