The TTR-1/SV is a video transformer designed for transmitting video signals from a single camera using one pair of twisted-pair cable. The device adapts the impedance of a 75Ω coaxial cable to the 100Ω impedance of a twisted-pair cable, ensuring reliable video signal transmission over distances up to 400 meters. The TR-1/SV transformer features opto-isolation between input and output, providing protection against:
- Lightning discharges
- Voltage differences and surges
- Electric currents in video signal cables
