Board Dimensions
(W x L x H approximate)
:
4.5” x 7.25” x 1.75” (114.3mm x 184.15mm x 44.45mm)
Stand-by Specifications:
When 12VDC/12AH battery is used, the unit provides 30 minutes of backup @ 10A.
Installation Instructions:
The AL1012ULXB must be installed in accordance with article 760 of the National Electrical Code, ANSI/NFPA 70 and
all applicable Local Codes.
1. Mount the AL1012ULXB in the desired location/enclosure.
2. Connect unswitched AC power (115VAC / 60Hz) to the terminals marked [L, G, N] (Fig. 1, pg. 2). Use 18 AWG or
larger for all power connections (Battery, AC input, DC output). Use 22 AWG to 18 AWG for power-limited circuits
(AC Fail/Low Battery reporting).
Keep power-limited wiring separate from non power-limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered to the terminals marked [+ DC –] (Fig. 1, pg. 2).
5. 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. Connect
battery to the terminals marked [+ BAT – ] (Fig. 1, pg. 2).
6. If it is required to connect appropriate signaling notification devices to [AC FAIL] and [BAT FAIL] supervisory
relay outputs (Fig. 1), use 22AWG to 18AWG wires.
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 (13.2volts).
Battery Test:
Under normal load conditions check that the battery is fully charged, check specified
voltage both at battery terminal and at the board terminals marked [+ BAT -] to ensure there
is no break in the battery connection wires.
Note:
Maximum charging current under discharge is 0.7A.
Note:
Expected battery life is 5 years; however, it is recommended changing batteries in 4 years
or less if needed.
AL1012ULXB
UL Recognized Power Supply/Charger
Overview:
