About the PowerPlus 3000 System
The PowerPlus 3000 system is used with CopperHead links, delivering electrical current to a
video camera equipped with a CopperHead Camera Unit by adding power to an SMPTE
Hybrid cable. The system consists of a camera-mountable PowerPlus adaptor at the camera,
and the HDX Power Supply, located some distance away (up to 2 km), and connected by
SMPTE Hybrid cable.
All of the signals on the two strands of fiber connecting the CopperHead Camera Unit and
the CopperHead Base Station are passed transparently through the PowerPlus and the HDX
Power Supply.
The standard PowerPlus provides up to 100 watts of power to the camera and accessories.
The High Profile PowerPlus can provide up to 150 watts.
The PowerPlus delivers a nominal 14 Volts to the camera through the battery plate, as well
as to a 4-pin XLR connector for powering additional accessories.
For applications where 24 volt power is required at the camera, the 12/24 power option
provides this voltage to two 3-pin Lemo connectors on the PowerPlus adaptor.

The first part of the fiber run can be made via “dry” tactical or infrastructure fiber, after
which the HDX power supply is placed in line to provide a powered SMPTE hybrid fiber
cable for the camera. Such a system is typically configured as shown in
Figure 1-1 and
includes the following components:
The Base Station can be separated from the HDX power supply on “dry fiber” (F) by more
than nine kilometers (5.6 miles) , where powered hybrid cable (H) can be run to the camera
for another two km (1.2 miles).
