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. Power supply: 176÷264VAC, 50Hz. Power supply output: 7A/12VDC. Voltage adjustment range: 12V÷15V. Efficiency: 83%. Protections: SCP, OLP, OVP. Dimensions: L=199, W=98, H=38 [+/- 2mm]. For mounting on a DIN rail, required bracket: PSDIN2.
