Altronix MAXIMAL33RD Access Power Controller w/ Power Supply/Chargers, 16 PTC Class 2 Relay Outputs, Dual 12/24VDC P/S @ 6A each, 115VAC, 2U
- 115VAC 60Hz., 3.8 amp
- Normally closed [NC] or normally open [NO] dry contact inputs (switch selectable)
- Sixteen (16) PTC protected outputs
- Maximum current per ACM8R-M output is 2 amp
- Individually selectable Mag Lock/Strike (Fail-Safe, Fail-Secure) solid state fuse protected outputs

Maximal 33RD rack mount access power controller distributes and switches power to access control systems and accessories. It converts a 115VAC 50/60Hz input into sixteen (16) independently controlled 12VDC and/or 24VDC PTC protected outputs. Outputs are activated by an normally open (NO) or normally closed (NC) 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. Outputs will operate in both Fail-Safe and/or Fail-Secure modes. The FACP Interface enables Emergency Egress, Alarm Monitoring, or may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the outputs.
