9. Power
9.1. Introduction
The CamlinxII head and base units can be connected with either a Hybrid cable (fibre
plus copper power conductors) or a fibre only cable. If a fibre only cable is used, the
head can be powered by one of the following;
1. Battery
2. Local +12V supply (front connector on head)
3. Camlinx Power Injector (PI-Camlinx)
The 125W Base power supply is designed to power both the head and the camera. The
head power supplies have enough capacity to power most cameras without additional
power supply modules.
9.2. Base power indication
On the front of the base unit is a row of vertical green
LEDs which indicate the power load on the base. The top
most LED is always illuminated when the base is powered
up. The other four LEDs show the loading on the base
with the lowest LED showing minimal loading, additional
LEDs show increased loading on the base

9.3. Hybrid fibre/power cable
The Camlinx 2™ power link system operates at 52 volts DC. 52 volts is supplied by the
base unit and is converted down to 12 volts at the head. Up to 110 watts (5 Amps) can
be supplied to a Camera up to a distance of 130m. At a maximum distance of 300m,
the power that can be delivered to the camera will be reduced due to cable losses to
approximately half this value. (see graph)
Power losses down the cable are incurred when using hybrid cable. These losses limit
the length of cable that can be used as eventually the voltage level at the head will not
be sufficient to power the camera. The following graph shows the power losses typical
down a hybrid cable.
