Overview:
Altronix AL176220 and AL176X220 are power supply/chargers that converts a 220VAC (working range 198VAC -
256VAC), 50/60Hz input into 12VDC or 24VDC output (see specifications). Units must be installed in accordance
with National and Local Electrical Codes and Regulations.

Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI and with all
local codes and authorities having jurisdiction. Product is intended for indoor use only.
See Terminal Identification Chart on page 3 for a description of each terminal function.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure’s upper keyholes over the two upper screws; level and secure. Mark the position of the lower
two holes. Remove the enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s
upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws
(Enclosure Dimensions, pgs. 7 and 8). Secure enclosure to earth ground.
2. Connect unswitched AC circuit (220VAC, 50/60Hz) as follows: Green branch wire (ground) connects to the
terminal marked , Line connects to the terminal marked [L], and Neutral connects to the terminal marked
[N] of the Inlet Appliance Connector. 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 (220VAC, 50/60Hz Input,
Battery Wires). Minimum 0.25” spacing must be provided.
3. Set the unit to the desired DC output voltage by either removing or leaving the jumper.
(Power Supply Output Specification Table).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
Input:
• Input 220VAC (working range 198VAC - 256VAC),
50/60Hz, 0.3A.
Output:
• 12VDC or 24VDC selectable output.
• 1.75A continuous supply current.
• Filtered and electronically regulated output.
• Short circuit and thermal overload protection.
Battery Backup:
• Built-in charger for sealed lead acid or
gel type batteries.
• Maximum charge current: 400mA.
• Automatic switch over to stand-by battery
when AC fails.
Supervision:
• AC fail supervision (form “C” contacts).
• Low battery supervision (form “C” contacts).
Visual Indicators:
• AC input and DC output LED indicators.
Added Features:
• Includes power supply, transformer, and enclosure.

5. Connect battery to the terminals marked [+ BAT –] on the power supply board (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 is desired, they must be lead acid or gel type.
6. Connect appropriate signaling notification devices to AC Fail and Low Bat supervisory relay outputs.
Note: AC Supervisory outputs must be connected to the zone of Alarm Control Panel or to visual
AC trouble indicator.
7. For Access Control Device connections refer to the Terminal Identification Chart.
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions the DC output voltage should be checked for proper
voltage level (see Power Supply Output Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified
voltage both at the battery terminal and at the board terminals marked [+ BAT –] to
ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 400mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in
4 years or less if needed.
LED Diagnostics:
Red (DC) Green (AC) Power Supply Status
ON ON Normal function.
ON OFF Loss of AC. Battery backup is powering output.
OFF ON No DC output.
OFF OFF Loss of AC. Discharged or missing stand-by battery. No DC output.
Terminal Identification:
Terminal Legend Function/Description
XFMR INPUT Low voltage AC input (28VAC, 56VA).
+ DC OUT –Continuous positive (+) DC power output voltage.
Common negative (–) output (ground).
+ BAT –Stand-by battery connections.
AC FAIL
NO, C, NC
Used to notify loss of AC, e.g. connect audible device or alarm panel.
Relay is normally energized when AC power is present. Contact rating 1A @ 28VDC.
LOW BAT
NO, C, NC
Used to notify low battery condition, e.g. connect audible device or alarm panel.
Relay is normally energized. Contact rating 1A @ 28VDC.
