How to choose signal lightning protection
The signal lightning arrester is mainly equipped with lightning protection devices on the communication signal line, mainly including: video signal lightning protection device, network signal lightning protection device, audio signal lightning protection device, control signal lightning protection device, etc., signal lightning protection device selection It is also equipped according to the condition of the equipment.
How to choose a signal arrester
1. Working voltage (depending on the working voltage of the equipment, choose the appropriate protection voltage for the lightning arrester)
2. Working frequency (depending on the requirements of the equipment for the insertion loss of the arrester, choose the lightning arrester with different bandwidth)
3. Interface standard (select lightning arresters of different interfaces according to the type of equipment interface (RJ11\RJ45\BNC, etc.), metric, and English)
4. Connection with other devices (whether or not the overvoltage is introduced or output due to connection with other networks)
5. Grounding condition (If the ground potential is unstable, the shielded and anti-interference arrester should be selected)
It is very important to protect the system communication against lightning protection. It is very important to select appropriate protection devices. The lightning protection products should be fully matched with the communication equipment.
The choice of lightning protection device should be matched according to the equipment it needs to protect. The equipment of the lightning protection device can not affect the operation of the original equipment first. Secondly, we are equipped with the lightning protection equipment that can protect the equipment!
