Signal lightning protection devices are mainly equipped with lightning protection devices for communication signals, mainly including: video signal lightning protection equipment, network signal lightning protection devices, audio signal lightning protection devices, control signal lightning protection devices, etc..The selection of signal lightning protection device should also be equipped according to the conditions of the equipment
【Type of protection signal】
When the signal level tends to low voltage, it becomes more susceptible to overvoltage.At the same time, electronic products have been involved in a wide range of industries.How to use a suitable signal overvoltage protector (signal arrester) is a big problem that plagues users. We usually consider the following main parameters: digital/analog; working voltage; working frequency; interface standards; five categories of use occasions.In summary, it includes:
1. High frequency (microwave/wireless communication)
2. Computer local area network, wide area network
3.Industrial automation control signal
4. Office communication network (data dedicated line, etc.)
5. Video system (Cable TV/CCTV)
[How to choose signal lightning protection device]
(1) Working voltage (select the lightning arrester with corresponding protection voltage according to the working voltage of the equipment)
(2) Operating frequency (according to the equipment’s requirements for the insertion loss of the arrester, choose arresters with different frequency widths)
(3) Interface standards (Surge arresters with different interfaces can be selected according to the equipment interface (RJ11RJ45BNC, etc.), metric system, inch system, etc.)
Connection with other equipment (whether due to overvoltage or output due to connection with other networks)
Grounding situation (if the ground potential is unstable, you should choose shielding and anti-interference arresters)
Choosing the right lightning protection device is the key to system communication lightning protection.
Choosing Hangzhou lightning protection equipment should be based on the equipment it needs to protect. ①It cannot affect the work of the original equipment, ②It is equipped with equipment with good lightning protection effect!
