1. Technical description.

1.1. General description.

The power supply unit is intended for the feeding of alarm system equipments, which require 12V DC supply voltage
and current load I=3A. The design enables simple changing of the output voltage, within the range of 12V÷15V DC, using a
potentiometer. The power supply unit is protected against short-circuit, overload and overvoltage.
