Chapter 3 - Camera - DC/DC Converter
External DC-to-DC converter
The voltage on output 4 of the connector is
13 or 24 V depending on the type of conver-
ter. The maximum power produced is 50
Watts.
Note:
The maximum power (50W) produced by
the external converter connected on the
camera "DC OUT" is ensured with a maxi-
mum triaxial cable length detailled in the
SPECIFICATION chapter.
Converter supply:
The voltage received on this receptacle
varies between 30 V DC and 52 V DC
depending on:
• The length and type of the triaxial cable
• The power consumed by the converter.
The - 5 V is used to delay starting of the con-
verter on camera power on to prevent the
Channel Control Unit power supply tripping
out.
If a DC-to-DC converter (even unloaded) is
connected to the camera while operating, the
safety system will cause the camera to trip
out.
The converter must be connected to the
camera with camera power off.
Light: the DC voltage is present on the con-
verter output.
