SEPARATOR WITH VIDEO BALUN D-SEP/HD-4/TR
DESCRIPTION The D-SEP/HD-4/TR has the following functions: galvanic separator , ground loop isolator - eliminates or reduces signal interferences resulting from the potential difference between devices and currents flowing through the signal mass. Video Balun - adapts 75Ω coaxial cable impedance to symmetrical cable impedance. Each input is protected by a specialized TVS diode.
The D-SEP/HD-4/TR consists of 4 independent (galvanically isolated) channels.
The D-SEP/HD-4/TR requires the proper connection. LINES (cable terminals) - signal from camera (symmetrical transmission line). DEVICE (BNC socket) - recorder, monitor.
It is important to pay attention to linking the adequate terminals: (+) and (-). Reverse connection would cause distortion of image.
