Network two-in-one lightning arrester

Short Description:

Video surveillance multifunctional surge protector, used for the protection of AC/DC power supply, video/audio signal and control signal of front-end equipment such as cameras, pan-tilts, decoders, etc., so as to effectively absorb the energy impact generated by surges and pass The grounding cable introduces energy into the earth. The camera protection with decoder adopts SV3 series, and the camera protection without decoder adopts SV2 series. Choose the corresponding product according to the working voltage of the camera. The multi-functional integrated design reduces the protection cost and installation difficulty, saves installation space, and greatly improves the comprehensive protection effect of the camera.


Product Detail

Product Tags

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.

Features of two-in-one lightning arrester:

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.

Installation method of two-in-one lightning arrester:

1. the network camera two-in-one lightning arrester is installed in series in front of the network camera port (the “INPUT” identification terminal is connected to the line, and the “OUTPUT” identification terminal is connected to the protected camera), and then the PE grounding terminal is welded or bolted to the ground grid with copper core wire.
2. Connection method of power line terminal of network camera two-in-one lightning arrester: two ends of power supply are connected with “L/+”and “N/-”respectively.
3. Connection of RJ45 network signal line of network camera two-in-one lightning arrester: it is installed in series, and RJ45 crystal head is directly plugged in.
4. The cross-sectional area of lightning protection grounding wire should be ≥2.5mm2 and be as short as possible. Installation of this lightning protection product requires that the grounding resistance is less than 4Ω, and the lightning protection performance is the best when the grounding wire and grounding resistance are qualified.
5. This lightning arrester is maintenance-free, and the working condition of lightning arrester should be checked and recorded in time after thunderstorm.
