Overview; Specifications; Power Supply Output Specifications; Installation Instructions - Altronix AL125220 Series Installation Manual

Altronix AL125220 and AL125X220 Power Supply/Chargers convert 220VAC (working range 198VAC - 256VAC),
50/60Hz input into two individually PTC protected auto-resettable 12VDC or 24VDC outputs (see specifications).
They are intended for use in Access Control applications and applications requiring an interface with Fire Alarm
Control Panels.
Input:
• 220VAC (working range 198VAC - 256VAC),
50/60 Hz, 0.3A.
Output:
• Two (2) 12VDC or 24VDC outputs.
• 1A total supply current @ 12VDC or 24VDC.
• Filtered and electronically regulated output.*
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.
*Note: When unit is powered by battery back up (AC Fail condition), the voltage range is 9.3V-13.2V and
19.55V-26.4V for 12 and 24 volt operation respectively.

The units should be installed in accordance with article 760 of The National Electrical Code and NFPA 72 as
well as all applicable Local Codes.
See Terminal Identification Chart on page 4 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 two 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. 7-8).
2. Power connections: Connect secondary (blue and yellow leads) from the transformer to the Power Supply
Board terminals marked [XFMR] (Fig. 1 - Application Diagram, pg. 5). 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.
