Altronix 8 fused outputs power supply/access power controller converts a 115V AC 60Hz input into 8 independently controlled 12V DC or 24V DC Fail-Safe and/or Fail-Secure outputs with a total of 4 amp at 12VDC or 3 amp at 24V DC continuous supply current. Outputs are activated by an open collector sink or normally open (NO) dry trigger input from an access control system, card reader, keypad, push button, PIR, etc. This unit will route power to a variety of access control hardware devices including mag locks, electric strikes, magnetic door holders, etc. The outputs will operate in both Fail-Safe and/or Fail-Secure modes. This unit is designed to be powered by one common power source (factory installed) which will provide power for both the board operation and locking devices, or 2 totally independent power sources, 1 providing power for board operation and the other for lock/accessory power. Input: Input 115V AC 60Hz rated at 1.9 amp. Output: 12V DC or 24V DC outputs; 12V DC at 4 amp supply current or 24V DC at 3 amp supply current. Class 2 Rated power limited outputs. Output ratings: Fuses are rated at 3.5 amp. Filtered and electronically regulated outputs (built-in power supply). Fire alarm disconnect input options: Normally open (NO) or normally closed (NC) dry contact input. Polarity reversal input from FACP signaling circuit. Built-in charger for sealed lead acid or gel type batteries. AL400ULXB (Power Supply Board) maximum charge current 0.7 amp. Automatic switch over to stand-by battery when AC fails. Zero voltage drop when unit switches over to battery backup (AC failure condition). Battery fail and battery presence supervision (form "C" contact). Wall mount enclosure for indoor use. Accommodates up to 2 12VDC/12AH batteries. Measures 12-1/4-inches width by 15-1/2-inches height by 4-1/2-inches depth. 1.125-inches and 1.375-inches combination knockouts.
