DESCRIPTION The TRO-8/400PV-RACK is designed to power with DC voltage and receive video signals from 8 TRN-1/400 devices (video baluns - transmitters) via twisted pair cable (UTP, FTP) over a distance up to 400 meters. The TRO-8/400PV-RACK overvoltage limiter effectively protects signal line carrying away the stroke current to the ground, due to above provides adequate overvoltage protection for electronic devices.
Video signals from cemaras connected to the TRN-1/400 transmitter inputs are sent to the TRO-8/400PV-RACK receiver via twisted-pair cable. Both transmitter and receiver units adapt 75Ω coaxial cable impedance to twisted-pair cable impedance, what guarantees the video signal transmission up to 400 meters. The TRO-8/400PV-RACK receiver supplies un-stabilized voltage (maximal up to 40V DC) to twisted-pair cable, and the TRN-1/400 transmitter converts it into 12V DC stabilized voltage, what enables power the cameras with thermostat.
All parameters concern twisted-pair cable category 5 with copper wires 0,5mm diameter (24 AWG).
