Power Distribution Modules
These Power Distribution Modules conveniently
distribute a single A.C. or D.C. input into nine
individual outputs, for centrally powering Video
Cameras, PIRs, Photobeams, etc. Each output is
protected with an auto-resetting PTC to protect a
shorted output from disabling the other outputs. A
visual LED power indicator is provided for each
output along with a single Master Power On/Off
Switch. The modules accept a 6 to 30 Volt A.C. or
D.C. power source (not included) which connects
either to the input terminal block or the 2.1mm D.C.
power jack located on the module. Two or more
outputs can be paralleled for additional current.

Instructions ELK-PD9
1. To remove the cover from the Power Distribution Module (ELK-PD9), use a small object like a screw driver to press into
the slots located on the end of the cover. Insure that the power switch is off.
2. Using Table 1 or Table 2 below, select an AC or DC Power Source that provides enough current to power the number of
devices to be used. The Power Source voltage must also match the device's voltage requirements. Mount the Power
Distribution Module near the Power Source that will be used to power the devices.
3. Connect the Power Source to the Power Distribution Module via the two Input Power Screw Terminals or the 2.1mm DC
jack(J1) located to the right of the terminals.
4. Connect a two conductor cable from the Power Distribution Module's Output terminals to the devices to be powered. If
desired, the total current draw can be measured at the Master Power Switch using an Ammeter while the switch is off.
5. Turn the Master Power Switch on, ensure all leds are on. Replace the plastic cover on the Power Distribution Module.

Table 2: Quick Power Supply Selection by Number of Devices
Select a column that closely approximates the power consumption of each device. For the
desired voltage, select the row that meets or exceeds the number of desired devices. The
appropriate Power Supply Model # is shown at left. NOTE: If a device consumes more than the
max. rating of a single PD9 output then parallel two or more outputs together to achieve the
desired capacity. Use additional PD-9's for every 9 devices or as required.
