The ELK DC Power Supply & Battery Charger (4 Amp, 12 Volt) is a complete switching power supply kit. Three individual PTC-protected outputs deliver 12VDC power to three sets of DC power terminals, perfect for a variety of alarm, surveillance, and access control applications. One LED for each set indicates whether or not voltage is present. The kit also features automatic resetting overload protection, a master On/Off switch, and automatic low battery cut-off to prevent the backup battery from going into a deep discharge.
