Description

The AQDX series are heavy-duty, self-contained, efficient, clean, offline switching power supplies, with linear-type performance, and are jumper selectable between 12 VDC at 6A and 24 VDC at 6A. The AQDX series have a dedicated lead acid battery(s) charger that obtains maximum battery life while providing 12 VDC or 24 VDC uninterruptible power for access control security systems. The field selectable AC input on AQD2, 4, and 6 models allows these power supplies to be powered anywhere in the world. The AQDX series have exceptional brownout capability with operation down to 85% of nominal voltage. The AQDX series have an extensive filtering system that provides linear output performance, and they are electronically protected against battery reversal, shorting, or overloading. All variants are Power limited output with thermal protection, AQD6 is power limited only when used with a distribution board. Each of these protective features will self-restore.

NOTE: Before connecting load and battery(s), ensure the 12V/24V jumper is moved to the desired voltage.

CAUTION: Damage can occur when switching the DC output voltage. Proper voltage must be confirmed before connecting devices.

500-25010_2

The AQDX series are UL Listed and have additional supervisory features:

•Battery disconnect relay when battery(s) are depleted

•Set of Form “C” relay contacts that indicate AC power failure

•Set of Form “C” relay contacts that indicate low battery(s)

•DC Output is Class II power limited

•Green LED for local “AC” on indication

Depending on load, low battery trouble indicates 50–75% battery capacity remaining. Input wiring to the unit should be enclosed in conduit secured firmly to the enclosure. The AQDX cannot be used to power a mercantile bell.
