Video coaxial signal lightning arrester

1、 Application and characteristics
This product is mainly used in coaxial computer systems and video monitoring systems to protect equipment from overvoltage and surge currents caused by induced lightning strikes, as well as damage to equipment caused by overvoltage and surge currents generated within the system. This product adopts a multi-level combination protection circuit, which has the characteristics of low protection level, fast response speed, reasonable structure, and convenient installation.

2、 Protection principle
The protective circuit of this product adopts a combined two-stage protective circuit. The first stage adopts a switch type protective device (the GDT port of the gas discharge tube is combined with an isolation resistor element that can withstand surge impact between stages, which can fully discharge most of the surge pulse current into the ground; the second stage adopts a voltage limiting protective device (the TVSS port of the transient diode with extremely fast response time effectively clamps the voltage at the output end, so that the equipment can work safely and normally.
