Securitron AQD4-8C1R2 AQD4 Series Switching Power Supply with Enclosure

Optimize your access control and security installations with the Securitron by ASSA ABLOY AQD4-8C1R2 switching power supply. Engineered for reliability, this AQD4 Series unit supplies a continuous 4A output and is field-selectable for 12V or 24V operation, making it ideal for mixed-device environments. With up to 16 independently controlled, power-limited outputs and UL-listed supervised circuitry, the AQD4 simplifies wiring and monitoring for multi-door access, surveillance cameras, and other security peripherals.

The built-in dedicated battery charging circuit and low-battery cutoff protect locking devices while ensuring dependable backup power during outages. High efficiency (up to 89%), thermal shutdown with auto-restart, and circuit breaker protection lower lifetime costs and reduce maintenance downtime. Whether you’re deploying enterprise access control, integrated surveillance, or facility monitoring systems, the AQD4-8C1R2 delivers the dependable, code-compliant power backbone installers and security managers expect. Add this switching power supply to your next security project or contact our team for system design guidance.
