Video Lighting Protection System

Updated on Nov.24, 2011

Brief Introduction

Video/Radio Signal Surge Protective Device is designed according to the IEC standard and National Standard. It can be used for single BNC terminal, 16 BNC terminals, F terminal and N terminal lightning protection.

This product is suitable for the monitoring system BNC terminal, matrix BNC terminal, optical transceiver BNC terminal, Video Camera BNC terminal as lightning surge protection.

This product is produced according to the discharging, clamping, filtering principles, that realized high efficient discharging lightning currents and resistance of EMP shock which caused by lightning currents. It has advantages of multi classes’ protection, extremely low residual voltage, perfect transmission performance, quick respond, large discharging capacity, simple installation and connection, easy maintenance.

DK Company can produce this product with different classes working voltage and various number of terminals according to the customer’s requirement. The 8/20us maximum discharging currents (Imax) can reach 10kA.
