The AQD5 series of heavy duty switching power supplies are highly reliable and designed to protect access control hardware with level output at the right voltage. These dual voltage supervised products have a battery charger with a lower battery disconnect, and dedicated voltage that helps the battery to charge faster even when it's under a large load. You can select either 5 Amp voltage at 12VDC or 3 Amp voltage at 24 VDC.
The AQD5 series has has an operating temperature that ranges from -4 to 104 degrees Fahrenheit, or -20 to 40 degrees Celsius. It has multiple protections against potentially destructive situations that will make you feel confident in using these with customers. The circuit breaker will reset itself to protect against thermal runaway, over-current and reverse battery faults. The unit will tolerate brownout or overvoltage input between 60 to 260 VAC. The fuse is also protected against surge for both AC input and DC output. Securitron has a MagnaCare lifetime replacement, no fault warranty if anything does go wrong with the unit.
The power supply's access control outputs are customizable with options for fire trigger and fuse/dry contact, fire relay only, or outputs with fire relay input. LED indicators and form "C" contacts allow you to remotely monitor AC failure or low battery are field customizable.
There are a total of eight models, all with field selectable 5 Amps at 12VDC or 3 Amps at 24 VDC, and class 2 power limited outputs. The AQD5 and AQD5-1R both have one output, but the latter also has one fire transfer relay with Normally ON and Normally OFF output that can be shifted when triggered, choice between latching or non-latching mode, LED trigger status indicators with multiple ways to trigger, and ground fault detection. The AQD5-4F and AQD5-4C both have four outputs, the 4F having a 2A rated fuse and the 4C having a 1.4A PTC fuse. The AQD5-8F, AQD5-8C, AQD5-8C1R and AQD5-8F8R models all have eight outputs. The 8F has a 2A fuse, and the 8C has a 0.72A PTC fuse. The 8C1R has a 1.23A PTC fuse and 1 fire relay, and the 8F8R has a 0.5A fuse with 8 access control relays.
The 1R is the only model with no UL listings. The AQD5, 4F, 4C, 8F and 8C all are UL 294, UL 603, ULCS318-96, and CAN/ULCS533-M87 listed. The 8C1R is UL 294 recognized. The 8F8R is UL 294, UL 603 and ULCS318-96 recognized.
The AQD5 series has a 14" by 9" by 3-1/2" enclosure that weighs 7.65 lbs, which supports up to two sealed gel AGM or wet lead acid batteries
