LKD309BNC / 8TV series video lightning protection device is designed for lightning protection TV monitoring system requirements for the design, mainly to solve the TV monitoring and control system for DVR video line by lightning induced high voltage and high current damage.
This product is specially suitable for the protection of TV monitoring system of coaxial cable remote transmission line, coaxial cable only need to enter the CCTV room first after LKD309BNC / 8TV series equipment, can effectively protect the back of the matrix, digital video recorders and monitors from lightning over-voltage, induced pressure and electrostatic discharge damage caused by lightning the destruction of. Suitable for railway communication system, mobile station, CCTV, CATV public television, monitoring system, satellite TV receiving system and VOD system etc..
Its main features are:
1 multilevel protection circuit, low residual voltage level, good protection effect, large flow capacity, fast response.
2 core components of international brand-name products, excellent performance, reliable work.
3 easy to use, no maintenance.

Three, equipment use instructions
Through the detection of high voltage pulse signal in the circuit, the high voltage and the destructive voltage will be limited to the voltage value of the equipment through the three level protection circuit of the lightning protection device, so as to achieve the purpose of lightning protection.
When used, it is connected to the "IN" port of the device outside the line which is easy to be induced by lightning, and the "OUT" port of the device is connected to the subsequent matrix, digital video recorder, monitor and other equipment. Connect the PE terminal of the device to the ground wire of the control center.
