1. Technical description.

1.1. General description.

The power supply unit is intended for supplying power to alarm system devices requiring 12V DC supply voltage and

current load of I=7A. The design enables simple change of the output voltage, within the range of 12V÷15V DC, by means of a

potentiometer. The power supply unit is protected against short-circuit, overload and overvoltage.
