Power network two-in-one lightning arrester, network two-in-one lightning arrester and network two-in-one surge protector are designed according to IEC and GB standards, which are mainly used for lightning electromagnetic pulse (LEMP) protection of various HD Network Camera and network signal lines, and are integrated multifunctional surge protectors.
1. the network camera two-in-one lightning arrester has large current capacity: 10KA(8/20μS), high-speed response (10-12ns) and low loss; 2. The design concept of two-in-one power supply and network lightning protection does not take up space and is suitable for surge protection of various high-definition network cameras; 3. It can effectively prevent equipment damage caused by instantaneous increase of potential difference between camera power supply and network equipment; 4. Two-stage series linkage protection is adopted internally, with low residual pressure and long service life; 5. The power surge protection port has LED failure indication (green: normal; Extinguish: invalid); 6. The network camera two-in-one lightning protector adopts integrated structure, small size, simple wiring and convenient installation.| MODEL:LH-AF/24DC | LH | Lightning pick surge protector |
