The QSD-RJ45-12 (24220) model power network combination surge protector is specifically designed for lightning protection of network camera terminals, protecting them from damage caused by lightning induced overvoltage, power interference, electrostatic discharge, etc. It has the characteristics of low residual pressure, low attenuation, easy installation, and large flow capacity.

Features

Suitable for situations where both computer network signals and power supplies require voltage protection, commonly used for home users' computers and power supplies to be protected simultaneously, and for network cameras to be protected from damage caused by induced overvoltage, operational overvoltage, and electrostatic discharge; Simultaneously equipped with lightning protection for signal power supplies of different voltage levels, the product features multi-level protection, large channel capacity, low voltage limit, fast response time, low insertion loss, and high transmission rate.

working principle

The surge protector is connected in series to the front end of the protected equipment. When the transmission line is subjected to induced lightning and other instantaneous overvoltage surges, the surge current flows through the protection branch of the surge protector, discharges it to the ground, and sets the induced overvoltage level within the allowable voltage range of the equipment, thereby ensuring the safety of the operating equipment.
