The Securitron AQD6 Series of switching power supplies are dual voltage supervised units with a battery charger designed to power magnetic locks, electric strikes, card readers, sensors, access control boards and other devices in access control systems. The AQD6 Series can also be used to power DC cameras and other DC locking equipment. These units provide field selectable 6A at 12 or 24 VDC with up to 16 independently controlled power limited outputs. The AQD6 is Securitron's first power supply series that meets UL 294 6th Edition. Dual-voltage 6A 12 or 24 VDC field selectable continuous output. Tolerates brownout or overvoltage input ± 15% of nominal voltage. Thermal shutdown protection with auto restart. Circuit breaker protects against overcurrent and reverse battery faults. Dedicated battery charging circuit prevents overvoltage on locking devices. Expandable up to 16 outputs; Class 2 power limited outputs. Available with a single relay fire trigger or individually fire trigger relayed outputs. MagnaCare lifetime replacement, no fault warranty. Supports up to two (2) sealed gel, AGM or wet lead acid batteries. High efficiency: 90% at 24V output, full load. Operating temperature is from -4 to +122F [-20 to +50C].
