AL624TE220
Power Supply / Charger
Overview:
AL624TE220 power supply/charger converts 220VAC input into 12VDC @ 1.2A of continuous supply current (see speci-
fications). This general purpose power supply has a wide range of applications for access control, security, and CCTV
system accessories that require additional power.

Installation Instructions:
1. Mount AL624 into power supply enclosure with nylon fasteners (Figs. 1-3, pg. 2) (four (4) supplied).
2. Mount power supply unit enclosure in the desired location.
3. Connect blue and yellow leads from transformer secondary to the terminals marked [AC].
4. Connect 220VAC power to the black and white flying leads of the transformer.
5. Unit is factory set for 12VDC output.
6.
Measure output voltage before connecting devices. This helps avoiding potential damage.
7. Connect devices to be powered to the terminals marked [+ DC] and [DC - BAT], carefully observing polarity.
8. Connect battery to the terminals marked [BAT +] and [DC - BAT] (battery leads included)
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
