1Protect sensitive Ethernet power supply circuits and network terminals such as IP phones and network monitoring equipment from damage caused by thunder induced voltage, power interference, and electrostatic discharge. 2The network twoinone thunder protection device, integrated design, reduces the protection cost and installation difficulty, reduces the space occupation, and maximizes the use of the equipotential protection principle to greatly improve the protection effect. 3Using RJ45 signal interface, directly connected to the computer network, the highest flow capacity can reach 10KA. The limit voltage can be as low as 15V, and the response speed is nanoseconds, which can fully protect the frontend monitoring equipment, the flow is easy to be large, highspeed response, low loss. 4The network twoinone design concept is suitable for digital network highdefinition cameras to protect the network and power supply. Threelevel surge protection, low residual voltage, fast response time and long service life. 5Integration, small size, simple wiring, convenient installation, reduce space occupation, has stable performance and high work efficiency and bring you more convenience.
