3 Description
The video compact power supply provides power up to 96 video indoor stations (without parallel connection) and up
to 4 camera modules. However, a maximum of 3 indoor stations may be connected in parallel.
In a parallel connection (simultaneous ringing of several indoor stations) the maximum number of internal units will
be reduced. In addition, only one station at one of the 4 video signal outputs is able to display a video image.
The active distributor distributes the video signal to up to 4 risers. The outputs and inputs are built symmetrically and
the positive video signal (+) may not be swapped with the negative video signal (-). Every riser and/or every output
must be equipped with a 75Ohm load resistor.
If more than 4 risers are available, external distributor can be connected and powered via the video compact power
supply. The video compact power supply is protected against overload and short circui.
Improper connection of the input / outputs should be avoided. If the video signal lines (e.g. V+/ V-) are accidentally
connected to the supply outputs (e.g. +22), it can result in damage to the video compact power supply.
