TTR-1/SV - VIDEO TRANSFORMER WITH OPTO-ISOLATION
The TTR-1/SV device is designed for video signal transmission from one camera via one pair of twisted-pair cable. The device adapts the impedance of a coaxial cable 75Ω to the impedance of twisted-pair cable (100Ω) ensuring video signal transmission over a distance up to 400 m.
The TR-1/SV transformer has an output opto-isolated from input, which protects it from:
- lightning discharges,
- voltage differences and strokes,
- electric currents in video signal cables.
