AL624
Power Supply/Charger
Overview:
AL624 power supply/charger converts low voltage AC input into 6VDC or 12VDC @ 1.2A or 24VDC @ 750mA of continu-
ous supply current (see specifications). 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 in the desired location/enclosure (mounting hardware included).
2. Unit is factory set for 12VDC. For 6VDC output cut jumper J2, for 24VDC output cut Jumper J1.
3. Connect proper transformer to the terminals marked [AC] (refer to Voltage Output/Transformer Selection Table).
Use 18 AWG or larger for all power connections (Battery, DC output).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
5. Connect devices to be powered to the terminals marked [+ DC] and [DC - BAT], carefully observing polarity.
6. Connect battery to the terminals marked [BAT +] and [DC - NEG] (battery leads included)
Note: To avoid damage connect batteries as follows:
- For 6VDC operation connect one (1) 6VDC battery.
- For 12VDC operation connect one (1) 12VDC battery or two (2) 6VDC batteries wired in series.
- For 24VDC operation connect two (2) 12VDC batteries wired in series.
Note: When batteries are not used, a loss of AC will result in a loss of output voltage.
