The ELK-P624 is a general purpose regulated power supply and battery charger. It is ideal for alarm, access control, and CCTV applications requiring up to 1 Amp continuous current. Automatic resetting "fuseless" overload protection means never having to return to a job site to replace a blown fuse. On-board diagnostic LEDs indicate the presence of the AC charging and DC output voltages. The output voltage can be set with a mini-jumper.
