Product Details

DB series serial port signal surge protector

Product Introduction

The DB series signal lightning arrester is a new generation of serial interface signal lightning arrester carefully designed and manufactured according to relevant standards such as IEC. It uses high-quality components as 8/20 μ S lightning protection. Divided into two series of D-type interfaces, 9-pin and 25 pin, it provides lightning and other surge protection between wires and ground for devices using D-type interfaces such as RS232, RS485/422, wired remote sensing, telemetry, and remote control, with a response speed of nanoseconds and low insertion loss. It has complete protection performance and excellent technical indicators, fully complying with international and domestic standards such as GB, IEC, VDE, etc.
