Securitron AQD2 Series Switching Power Supply

The Securitron AQD2 Series is a high-efficiency dual voltage switching power supply engineered for the most demanding access control systems. Designed as a UL Listed supervised unit, the AQD2 provides a continuous 2 Amp output at either 12VDC or 24VDC, making it a versatile choice for powering magnetic locks, electric strikes, and card readers. With an efficiency rating of up to 85%, this power supply reduces heat generation and energy costs while significantly extending the operational life of your electrified door hardware.

Optimized Power Management and Battery Backup

The AQD2 Series features a dedicated battery charging circuit that ensures your backup batteries stay topped off without the risk of overvoltage. For mission-critical security, the unit includes a low battery cutoff (9V for 12V settings and 18V for 24V settings) to prevent deep discharge and protect battery health. This field-selectable unit is also equipped to handle brownout or overvoltage fluctuations of ± 15%, maintaining a stable and clean power flow during inconsistent electrical conditions.

Reliable System Protection and Supervision

Safety and reliability are at the core of the Securitron AQD2. It comes standard with thermal shutdown protection featuring an auto-restart function, alongside a circuit breaker to guard against overcurrent and reverse battery faults. Whether you are managing a single opening or a complex multi-door environment, the AQD2 is expandable up to 16 independently controlled outputs, providing the flexibility needed for enterprise-level security integration.
