DESCRIPTION The TR-16H/DC/R19 is designed to video signals transmission and power supplying via twisted-pair cable (UTP, FTP). The device adapts the impedance of coaxial cable 75Ω to the impedance of symmetrical line, ensuring transmission of video signal up to 400m @ PAL (twisted-pair cable category 5) and eliminates asymmetric interferences. Video signal is sent over one pair of a twisted-pair cable, the remaining three pairs are used for supplying power.
The device consists of 4 independent power modules (see diagram below) which allows for various configurations. 12V DC power sending allows to use the TR-1M/70 and TR-1PV/70. Some part of outputs can also be powered by 12V, the others eg. by 40V what enables power sending for long distances (application with TRN-1/400, ZK-40/6 or ZK-40/16).
