ELK P624 Specsheet
Power Supply & Battery Charger
ELK-P624
The ELK-P624 is a general purpose regulated
power supply and battery charger. It is ideal for
alarm, access control, and CCTV applications
requiring up to 1 Amp continuous current.
Automatic resetting “fuseless” overload protection
means never having to return to a job site to
replace a blown fuse.
On-board diagnostic LEDs indicate the presence
of the A.C. charging and D.C. output volt ages. The
output voltage can be set with a mini-jumper .
Features
• Selectable 6, 12, or 24 V olts D.C. Operation.

6 VOLT MODE
For 6 volt output, remove the small black mini-jumper from
the header pins marked JP1 and JP2. (See Figure 1 above)
Then connect a 12Vac, 40VA transformer to the AC
TRANSFORMER terminals and connect a 6V battery to the
red (+) and black (-) battery wires. The mini-jumper may
be discarded or stored for later use by placing one side
onto a single header pin.

12 VOLT MODE
For 12 volt output, place the small black mini-jumper on the
header pins marked JP1. (See Figure 1 above) Make
certain that header pin JP2 is vacant. Connect a 16.5 Vac,
40VA transformer to the AC TRANSFORMER terminals and
connect a 12V battery to the red (+) and black (-) battery
wires.
24 VOLT MODE
For 24 volt output, place the small black mini-jumper on the
header pins marked JP2. (See Figure 1 above) Connect a
24 Vac, 40VA transformer to the AC TRANSFORMER
terminals and connect a 24V battery to the red (+) and black
(-) battery wires.
