Description
一、Product description
Lefedi's two-in-one network lightning protection device is designed with reference to the national standard GB/T18802.21-2004/IEC61643-21:2000. The rail power supply network two-in-one lightning protection device (SPD) is mainly used for monitoring systems of various digital network cameras The all-round surge protection of power supply and network signal system is an integrated multi-function surge protector; it has the characteristics of large current capacity, low limit voltage, fast response speed, and convenient installation, which can fully protect the latest technology network monitoring equipment .
二、Features
1. Large flow capacity: 10KA, high-speed response (10-12 nanoseconds), low loss;
2. Adopting the two-in-one design concept of power supply and network, suitable for lightning protection of network cameras;
3. It can effectively prevent equipment damage caused by the instantaneous increase of the potential difference between the power supply, network and other equipment;
4. Adopt multi-level surge protection, low residual voltage, fast response speed and long service life;
5. Integrated, small size, easy wiring, 35MM guide rail installation design, easy installation.
