Securitron AQD4-4C1 4A Dual Voltage Power Supply, 4 Outputs, 1 Amp PTC Polyswitch Fire Alarm Interface

Deliver dependable, industry-grade power to your access control, surveillance and monitoring systems with the Securitron by ASSA ABLOY AQD4-4C1 power supply. Built for commercial and enterprise security deployments, this 4A dual-voltage power supply supports field-selectable 12V or 24V output and provides four protected outputs with 1A PTC polyswitches to isolate faults and keep critical devices online.

The AQD4-4C1 simplifies installation and ongoing maintenance: a dedicated battery charging circuit ensures backup readiness, thermal shutdown and circuit-breaker protection guard electronics, and UL-listed configurations ease code compliance. With up to 89% efficiency, it reduces operating costs and heat generation—important for control rooms and densely populated enclosures. The integrated fire-alarm relay interface lets you tie power behavior into life-safety systems for coordinated responses.

Ideal for door controllers, mag locks, readers and surveillance cameras, the AQD4-4C1 delivers secure, efficient power distribution for any access control layout. Contact your sales representative to specify the AQD4-4C1 for your next security or monitoring project, or add it to your BOM for reliable, long-term performance.
