2.5 REMOTE POWER SECTION
2.5.1 MAIN POWER SECTION
CAM Racer is basically remote powered from its base station. The basestation unit is able to source up to
140W of power for the camera at 450m of 9.2mm SMPTE cable. For longer runs the amount of available
power will decrease as shown on the following curve.
An optional battery support (V-lock or AB Gold mount) enables the CAM racer and its camera to be locally
powered by a battery.
A key feature of the Cam racer is the automatic switching between remote power and battery power without
power loss for the CAM racer and its camera. On very long lengths of SMPTE a temporary sudden extra
consumption (camera startup, accessory startup) may draw too much power regarding the loss of the
installed SMPTE cable. In this case the CAM racer will detect power drop and will switch on the battery and
come back on the remote power supply to save battery energy.
Note: The power curve above represents power dissipated by a pure resistive load, camera inrush current or
accessories inrush current may exceed those limits and make the internal converter to stop briefly and
restart. We improve our power section as converters with less load sensivity arrive on the market.
For this kind of application we suggest using our automatic battery backup principle.
2.5.2 8.4V REGULTATOR OPTION.
CAM racer is also designed for small power consumption devices like Canon C300/C500.
Upon request the remote power section is suppressed at both ends. The lock battery option powers the
Cam racer and fits an internal hi efficiency voltage regulator to deliver 8.4Volts 32Watts for the Canon
Camera over a dedicated D-Tap connector.
Upon request the 8.4V regulator can also be fitted on regular units with a dedicated D-TAP output.
