Securitron AQD4 Series Switching Power Supply
The Securitron AQD4 Series represents the pinnacle of reliability for access control power supplies, delivering a robust 4 Amp continuous output. As a UL Listed supervised unit, the AQD4 is engineered to support larger-scale security deployments requiring consistent 12VDC or 24VDC power. With an industry-leading efficiency rating of up to 89%, this switching power supply minimizes heat generation, slashes operating costs, and ensures the maximum longevity of your connected electrified locks and controllers.
Intelligent Power & Battery Supervision
Equipped with a dedicated battery charging circuit, the AQD4 Series provides superior protection for your backup power system, preventing overvoltage to sensitive locking devices. To ensure system integrity during prolonged power outages, the unit features an integrated low battery cutoff (9V for 12V settings and 18V for 24V settings), protecting your batteries from permanent damage caused by deep discharge.
Precision Engineering for Maximum Uptime
The Securitron AQD4 is designed to perform in unstable electrical environments, tolerating brownout and overvoltage fluctuations of ± 15%. For comprehensive system safety, it includes thermal shutdown protection with auto-restart and a built-in circuit breaker to shield against overcurrent and reverse battery faults. This field-selectable unit can be configured with up to 16 independently controlled outputs, offering the scalability required for sophisticated security integration projects.
