Two-in-one network surge protector, integrated multi-protection (Power over Ethernet surge protector), comprising two parts: power and network signal surge protection. Primarily used to protect sensitive Ethernet power and network terminals like IP phones and network surveillance equipment from damage caused by lightning-induced voltage, power surges, and electrostatic discharge. The integrated design reduces protection costs and installation complexity, minimizes space occupation, and utilizes the principle of equipotential protection to significantly enhance the protection effect. The RJ45 signal interface connects directly to the computer network, and the maximum discharge current capacity can reach 10KA. The limiting voltage can be as low as 15V, with response speeds in nanoseconds, effectively protecting front-end monitoring equipment. Features high discharge current capacity, high-speed response, and low loss, making it suitable for high-definition digital network cameras to protect network + power. Offers three-level surge protection with low residual voltage, fast response time, and long service life, all in a compact size for simple wiring and installation.
