AQD6-16C

Description

The AQD6 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 AQD6 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 allows these power supplies to be powered anywhere in the world. The AQD6 series have exceptional brownout capability with operation down to 85% of nominal voltage. The AQD6 series have an extensive

filtering system that provides linear output performance, and they are electronically protected against battery reversal, shorting, or overloading. Power limited output with thermal protection is available with Models AQD6-8F, AQD6-8C, AQD6-16F, AQD6-16C AQD6-8F8R, and AQD6-8C1R; nonpower limited in Model AQD6. Each of these protective features will self-restore.

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

CAUTION

Damage can occur when switched with DC output load. Proper voltage must be confirmed before connecting devices.

The AQD6 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.

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 AQD6 cannot be used to power a mercantile bell.

Specifications

AC Input: L, N, G - 3P Terminal block

Safety block with recessed hardware insulation accepts up to 12 AWG

L= Line, N= Neutral, and G = Ground

AC Input .........................................................120–240 VAC / 240W AC Input Frequency…………………… ............................50 to 60 Hz

AC LED Indicator (Panel mounted on the enclosure door)

The AC indicator is a green LED. This LED off with AC at the terminals would indicate a blown fuse link. A blown AC fuse link would indicate catastrophic failure and must be returned to the factory for repair.

AC Input Voltage Selection

CAUTION

To prevent damage, the power supply board must be configured for the proper voltage before applying line voltage.

NOTE: Once the link is cut, there is no conversion back to 120 VAC. There is a removable link located at the top right of the power supply board. This link is cut and removed to convert to 240 VAC.

DC Output Voltage Selector Jumper

CAUTION

To prevent damage, the DC load and battery(s) connections are removed before switching selector switch up or down.

The jumper is slightly left of center near the AC terminal block, and is marked with "VOLTAGE SELECT 12V / 24V". The jumper is moved to the appropriate pins to configure the output voltage.

DC Outputs: 2P Terminal block

NOTE: There is up to a 10-second delay for initial turn on.

Fault reporting relay rating: 32 VDC, 120 VAC, 1A

The battery charger is precision set to float charge 12V or 24V sealed or wet lead acid batteries. A 12-inch battery cable assembly is provided that plugs from module to battery: Red (+), Black (–) Neg.

UL Approvals for AQD6

UL 294, 6th Edition – Access Control System Unit

Endurance Test Level 1 Attack Test Level 1 Battery Standby Test Level 4

UL 603 – Power supplies for Use with Burglar-Alarm Systems UL 1481 – Power Supplies for Fire-Protective Signaling Systems ULC S318-96 – Power supplies for Burglar Alarm Systems

ULC S533-02 – Standard for Egress Door Securing and Releasing Devices

For ULC-S318-96 compliance, the power supply battery fail line must be connected to and monitored by a control panel trouble zone.

• NOTE 1: The AQD6 uses a standard power supply enclosure, not an attack proof' enclosure. As such, the AQD6 should not be used to power a mercantile bell.
• NOTE 2: When using a battery that is not housed inside the power supply enclosure, the battery leads require protection from the enclosure via the use of conduit.
• NOTE 3: When using the AQD6B in another enclosure, minimum standard spacing between live electrical circuits shall be taken into account.

Maintenance

The power supply and stand by battery(s) should be tested at least once a year as follows:

• 1. CHECK LED's for normal state: AC ON Green, Trouble Normal ON Green, DC ON Red.
• 2. CHECK output voltage with normal load (assures proper voltage to float charge batteries): For 12V setting, voltage should read 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.

Battery Selection

The table below shows typical standby time in hours for various loads and batteries. The table works for either 12 VDC or 24 VDC. The AQD6 was evaluated at UL with a 75 Ah sealed lead acid battery.
