CCTV Surge Protector

CCTV surge protector is a single channel, in-line, coaxial multi-stage video surge protector for analog cameras or head-end applications. CCTV camera surge protector is designed to provide multi-stage surge protection for one channel of video. The unit has MNC type connectors at the input and output for connection to the coax and is ideally suited for small or restricted spaces where a single line of video needs to be protected. CCTV Surge Protector provides power to the camera with the same unit.

Installation and Maintenance

1. Fix the surge protective device on the wall or place the plane, connect the wire according to drawing.

2. PE connect with the earthing, Earth resistance should accord with the standard of lightning protection.

3. The distance should be within 1 meter between being protection device and surge protective device.

4. Surge protective device will damaged and signal interrupter when maximum continuous operating voltage overrun.

Note: Lightning protection is probabilistic protection, and we cannot provide 100% protection.

First, lightning discharge itself has a certain degree of randomness, and lightning parameters have certain statistical properties, which determines that all protective measures based on these statistical characteristics of lightning parameters cannot provide 100% protection. Such as: direct lightning protection-shielding characteristics; lightning current amplitude, waveform, etc. have statistical properties;
Second, the lightning protection equipment cannot prevent the formation of lightning flashes;
Third, lightning protection devices cannot ideally eliminate all interference voltages/currents. The fundamental purpose of taking protective measures is to ensure that most of the energy caused by interference does not spread to the vulnerable parts of the device and the staff.
Finally, the cost of protection against high-level surges with a small probability of occurrence has risen sharply.

Technology SPD parameter(Note:According to user requirement ,can be customized Uc=140V,440V,550V,voltage range of range of the SPD):

Tip: How can I distinguish the quality of the lightning arrester?

1. It can be seen from the reaction time: determine whether the lightning arrester can respond in time and quickly discharge the lightning current.

2. It can be seen from the insertion loss: this refers to the installation of a lightning protector, the impact of this lightning protector on the line, the smaller the better

3. It can be seen from the number of impact resistance: determines the service life of the lightning arrester. Generally, the gas discharge tube will not drop after being placed for a period of time. If you want to check its quality, you can use an adjustable high-voltage DC power supply to test .
