PSU12V3A8OC 12Volt @ 8 Amp Power Supply Unit with Battery Back up , hinged lid, tamper switch and lockable enclosure designed specifically for Access Control applications.
Description - An 8 Amp 12V (13.7) PSU with 2 separate outputs designed specifically for Access Control applications. The Unit contains two separate outputs PCB’s, one maintained output and the other switched, typically via a Fire Alarm Panel. One output PCB is permanently active and provides 8 x 1A individually fused connections that typically supply the access control panels. The second output PCB also has 8 x 1A individually fused connections, but is user selectable by applying a low current 12V DC feed to the "Fire Enable” terminal on the PCB. This switched output will power the locks so that if the fire alarm is activated all the power to the locks is dropped thus allowing free egress. The PSU houses and charges two 12V 7Ah, or one 12V 12Ah or one 12V 17Ah VRLA batteries. The unit has separate SPCO (Single Pole Change Over) contacts for "Low Volts” and "Mains Fail” monitoring and includes Battery Deep Discharge Protection. Enclosure includes a hinged lid, tamper switch and lock.
