Securitron AQD4B Amp Dual Voltage Power Supply Board Only

Keep access control, security, and surveillance systems powered and protected with the Securitron by ASSA ABLOY AQD4B power supply board. Designed for professional installations, this dual-voltage power supply board delivers a dependable 4A continuous output and can be field-selected for 12V or 24V operation to match a wide range of locks, controllers and cameras. The AQD4B supports up to 16 independently controlled power-limited outputs when used in system configurations, and includes a dedicated battery charging circuit plus low-battery cutoff to extend battery life and prevent overvoltage to locking devices.

Engineered for commercial security environments, the high-efficiency switching design (up to 89%) reduces operating costs and heat, while built-in thermal shutdown, circuit breaker protection and brownout tolerance ensure resilient performance in harsh conditions. UL listing and ASSA ABLOY’s MagnaCare lifetime replacement provide peace of mind for integrators and facilities managers. Specify the AQD4B board for reliable, code-compliant power in access control, monitoring, and surveillance projects — or contact your distributor to integrate it into your next deployment.
