TR-8H/DC/R19 is designed for video signal transmission and power supply via twisted pair cable (UTP, FTP)The device adjusts the impedance of a 75Ω coaxial cable to the impedance of a symmetrical cable, ensuring video signal transmission up to 400m @ PAL (twisted pair of 5 categories) and eliminates asymmetric interferenceThe video signal uses one pair of twisted pair cables, the other three pairs are used to transmit the supply voltage
The device consists of 2 independent power modules (see diagram below) which allows for different configurationsThe 12V DC power supply transmission allows the use of TR-1M/70 and TR-1PV/70Some of the outputs can also be powered by 12V, the rest, e.g. 40V, which allows the transmission of power over longer distances (application from TRN-1/400, ZK-40/6 or ZK-40/16)
