Rev. A, 04/13

Overview of AQD3B Series Module

The Securitron AccuPower AQD3 offers clean, steady and accurate power output for peak performance of access
control equipment plus flexibility unmatched by any power supply/battery charger on the market today.

Universal AC input with brownout tolerance to 60VAC
Tolerates and protects against input voltage fluctuations.
External LED AC power indicator
Form “ C“ contact for AC power fail notification
Dedicated voltage for battery charging even under full load
Low battery disconnect prevents deep discharge of batteries
PTC protection for Thermal Runaway and Current Overload Short Circuit and Reverse Battery protection—

will auto restart without removing load.

AQD3B and AQD3 provide a single Class 2 power limited output. The output can be divided into additional channels
using any of the optional power distribution boards: PDB4, PDB8, PDB-8F8R, PDB-8C8R, PDB-8C1R or PDB-1R.

Applications

The AQD3 Series can be used with electrified access control equipment in conjunction with access control systems
and fire/burglary systems including most electrified locking hardware and latches, card readers, keypads, electric
strikes, REX and motion detectors and more.

Pre-Installation Survey

Before installing the AQD3 Series, the mounting location should be determined and assessed for the following:

Availability of AC power service
Protection from vandalism and tampering
Sufficient clearance for air circulation and heat dispersal

CAUTION: Check with your local code inspectors to ensure your compliance with the National Electrical
Code (ANSI/NFPA 70), (Canadian Electrical Code for Canada) or equivalent and any additional licensing
and wiring requirements for your jurisdiction.

A. Installing the Power Module

1.

Select mounting location so that AC input conduit can be aligned to maintain separation with DC power
outputs.

Ensure unit is mounted with sufficient airflow to prevent heat buildup.

IMPORTANT: AC Power input is not power limited. AC lines must be enclosed in approved

conduit. AC Input lines must be separated by at least ¼” from Class 2 power limited output

wires.

Mark board mounting hole locations and drill. Install four 6-32 x1/4 mounting screws appropriate for the
mounting location, leaving enough hardware exposed to install standoffs. Install standoffs. Place star
washer on any one of the three standoff locations corresponding to a mounting location on the board that
has a metal ring.

Affix board to standoffs with provided metal screws.

IMPORTANT: User is responsible for observing all electrical and code requirement when
installing in self-provided enclosure or mounting location.
