Overview:
The AL176UL is a power limited power supply/charger that converts a 115VAC / 60Hz input, into 12VDC or 24VDC
output, (see specifications). They are intended for use in applications requiring UL Listing for Access Control (UL294).
It must be installed in accordance with National and Local Electrical Codes and Regulations.
Specifications:
•ULListed - U.S. and Canada for Access Control Systems (UL294).
Class 2 rated power limited outputs.
Input 115VAC/60Hz, .6 amp.
Field selectable 12VDC or 24VDC power limited output.
1.75 amp continuous supply current @ 12VDC or 24VDC.
Filtered and electronically regulated output.
Maximum charge current: 400mA.
Automatic switch over to stand-by battery when
AC fails (zero voltage drop).
AC fail supervision (form "C" 1 amp @ 28VDC).
Low battery supervision (form "C" 1 amp @ 28VDC).
AC input and DC output LED indicators.
Short circuit and thermal overload protection.
Includes power supply, transformer, enclosure and battery leads.
Enclosure Dimensions: 8.5”H x 7.5”W x 3.5”D
Power Supply Output Specifications:
Output VDC Jumper Max. Stand-by Load DC Max. Alarm Load DC Battery (optional)
12VDC Jumper Removed 1.75 amp 1.75 amp 12VDC
24VDC Jumper On 1.75 amp 1.75 amp 24VDC
Stand-by Specifications:
Output 4 hr. of Stand-by &
5 Minutes of Alarm
12VDC / 7 AH Battery Stand-by = 1.25 amp
24VDC / 7 AH Battery Alarm = 1.25 amp
Installation Instructions:
The AL176UL should be installed in accordance with article 760 of The National Electrical Code or NFPA 72 as well as
all applicable Local Codes.
See Terminal Identification Chart on page 2 for a description of each terminal function.
1. Mount the AL176UL in desired location.
2. Connect AC power to the black and white flying leads of the transformer. Secure green wire lead to earth ground.
Use 18 AWG or larger for all power connections (Battery, AC input). Use 22 AWG to 18 AWG for power
limited circuits (DC output, AC FAIL and LOW BAT supervisory relays).
Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum .25” spacing must be provided.
3. Set the AL176UL to the desired DC output voltage by either removing/leaving jumper.
(see Power Supply Output Specifications).
Note: Measure output voltage before connecting devices. This helps avoid potential damage.
4. Connect battery to terminals marked [+ BAT -] on the unit (battery leads included). Use two (2) 12VDC
batteries connected in series for 24VDC operation.
Note: For Access Control applications, batteries are optional. When batteries are not used a loss of AC will result
in the loss of output voltage. When the use of stand-by batteries are desired, they must be lead acid or gel type.
