The power supply unit is intended for 230V AC mains supply to alarm system devices, which require 12V DC voltage and current efficiency of I=10A. 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 a short circuit, an overload, a surge or over voltage. Power supply: 176÷264VAC/ 50Hz. Power supply output: 10A/12VDC. Voltage adjustment range: 12V÷15V. Efficiency: 83%. Protections: SCP, OLP, OVP. Dimensions: L=199, W=110, H=50 [+/- 2mm]. For mounting on a DIN rail, required bracket: PSDIN2.
