1) Product Description:
Video signal surge protective device(called: SPD)is designed, produced and tested according to the IEC61644standard and Q/DK04-1999 corporate standards relevant industry standards, the quality of this product is control strictly according to ISO9001 quality control.
The product is applied to video surveillance systems, matrix BNC connector, Optical BNC interface, the camera BNC interface lightning surge protection. It can effectively prevent overvoltage and over current which are induced by lightning or industrial noise and other factors, and other transient surge voltage on the system or equipment or cause permanent damage or momentarily interruption and other hazards.
◆It is suitable for single-channel video BNC interface lightning surge protection.
◆Core components are selected international brands; they have high reliability, multi-level protection, and residual depression.
◆It is designed with advantage of low-capacity, excellent transmission performance, large intake capacity, fast response time and long lifetime.
◆It is use for monitor system, (such as video matrix switchers, cameras, video surveillance equipment, video distributor, etc.) video line surge protection.
