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.

• 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

Maintenance

The power supply and standby batteries should be tested at least once a year as follows:

1. CHECK LEDs for normal state: AC ON Green, Trouble Normal ON Green (Amber LED indicates trouble), DC ON Red.

3

2. CHECK output voltage with normal load (assures proper voltage to float charge batteries): For 12V setting, voltage should read

AQDX

PCB

between 13.6 VDC and 13.8 VDC; and for 24V setting, voltage should read between 27.1 VDC and 27.6 VDC.

3. DISCONNECT AC input: AC LED should be off, and all other LED’s should remain normal.

4. CHECK DC output to be above 12.0 VDC for 12V setting and 24.0 VDC for 24V setting (checks standby batteries to be operational).

5. APPLY AC and VERIFY AC LED ON.
