Securitron AQD4-8C2 AQD4 Series 4A Dual Voltage Power Supply with Enclosure, 8 Outputs, 2A PTC Polyswitch

The Securitron AQD4-8C2 power supply delivers dependable, professional-grade power for access control, CCTV, and security monitoring systems. Built by Securitron by ASSA ABLOY, this AQD4 Series power supply provides a single 4A continuous source selectable for 12V or 24V output, plus eight independently protected outputs with 2A PTC polyswitches — ideal for driving maglocks, cameras, and controllers while isolating faults.

Engineered for mission-critical security applications, the AQD4-8C2 is UL-listed and supervised, with a dedicated battery charging circuit and low-battery cutoff to safeguard locking devices and ensure predictable failover during outages. Its high efficiency (up to 89%) reduces heat and power draw, lowering operating costs for large surveillance and monitoring deployments. Built-in circuit breaker, thermal shutdown with auto-restart, and reverse-battery protection minimize service calls and simplify field maintenance.

Choose the AQD4-8C2 when you need a compact, reliable power distribution solution for access control panels, cameras, alarm systems, and other low-voltage security equipment. Contact us to specify the unit for your project or order now to secure consistent power for your security infrastructure.
