APPLICATION
The ELK-P412 is a general purpose high current power supply and battery charger. It is ideal for alarm, access control,
and CCTV applications requiring up to 4 Amps. The ELK-P412K is packaged complete with enclosure, battery, and AC
power cord. It distributes 12 Volts D.C. power to three (3) sets of DC power terminals, each having a voltage present
indicator LED and automatic resetting overload protection. Built-In Low Battery Cut-off circuit protects the battery from
deep discharging if AC power is lost for an extended period of time.

INSTALLATION / OPERATION
1. Set Master Power Switch (SW1) to Power Off.
2. Mount enclosure in secure location near an AC power
outlet that is not controlled by a switch.(supplied
power cord is 6 feet long)
3. Connect devices to be powered to the screw
terminals for DC output.The power distribution board
has three sets of outputs, each set is limited to 2.5
amps. If a device requires more that 2.5 Amps, parallel
two sets of terminals. (DO NOT EXCEED 4 AMPS)
4. Connect Battery to the battery wires, observe polarity.
5. Plug in the AC cord.
Warning High Voltage
is now
present at the power supply AC input terminals.
6. Set the Master Power Switch to Power On. The LEDs
at the power outputs should be on (if any are off,
check for overloaded condition). The connected
devices are now powered.
7. If AC power is lost, the Low Battery circuit will
disconnect the battery if it's voltage drops below 10
Vdc. This helps to prevent "deep discharging" of the
battery.
