The power supply unit is intended for the feeding of alarm system equipments, which require 12V DC supply voltage and current load I=5A. 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. Power supply: 85÷264VAC / 120÷370VDC. Power supply output: 5A/12VDC. Voltage adjustment range: 12V÷15V. Efficiency: 80%. Protections: SCP, OLP, OVP. Dimensions: L=159, W=97, H=38 [+/- 2mm]. For mounting on a DIN rail, required bracket: PSDIN1.
