1amp Alarm Power Supply

1Amp alarm power supply unit (PSU) is a device that provides a stable, regulated DC power source for alarm systems, typically with a 1 Amp (1000mA) output current. These units are designed for low-power security applications like access control, CCTV, and general alarm systems. Key features often include a universal mains input, built-in overcurrent protection, and the ability to charge a backup battery for operation during power outages.
