4.2 Power Supply
Via the TechniLAN 8/8 passiv 13V wall power supply, all TechniLAN participant sockets are
supplied with power. If a receiver, connected at the socket, has a higher voltage, for example 18 V
for the horizontal polarization, then this receiver takes over with supplying the participant sockets
with power with which it is connected. The receiver voltage is fed through to the multi-switch
and/or the LNB so that the reception level desired by the receiver can be reached.
The TechniLAN 8/8 passiv is designed so that it can take over supplying power to the multi-
switches and the LNBs. Care should be taken that the maximum power allowed by the wall power
supply is not exceeded, especially in the case of systems without power supplies, which is for
example possible with the TechniSwitch 5/8.
The maximum power consumption can be estimated by using the following formula:
Vert max
mA 350 I n I
+ ⋅ =
Here n is the number of connected TechniLAN sockets. In this manner, it is assumed that the
power consumption for the sockets is at 350 mA for conditions that are not ideal, for example
lengthy coaxial cables.
I
Vert
is the power which is fed into the distribution system (multi-switch and LNB). This is normally
a maximum of 400 mA.
When necessary, a wall power supply is to be connected to the multi-switch which then supplies
the distribution system with power. This is also true when a receiver is not capable of supplying
the required power for the distribution system and the TechniLAN socket.
