VIDEO BALUN TR-16/DC-RACK
DESCRIPTION The TR-16/DC-RACK 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 (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 TR-16/DC-RACK can be powered from one or two outer power adaptors (A or B).
Each of power line is protected by the polymer fuse and has a green LED indicator, which informs about its operation (the LED light is off when the power is off). When one of the outputs is overloaded the resistance and polymer fuse temperature are increasing (>100°C), and the LED indicator ligth is off. When the fuse is warmed up, the flowing current has small value. If the overloaded reasons are stoped, the fuse returns to the prevoius state.
In device, depending on current consumption there is a voltage drop on polymer fuses: 160mV at I=0.5A ; 300mV at I=0.7A ; 340mV at I=1A.
