Signal SPD
Signal surge protective device (Signal SPD) is actually a signal lightning arrester, which is installed in series in the signal transmission line, usually at the front end of the equipment, to protect the subsequent equipment-all kinds of signal lines and equipment, and prevent lightning waves from influencing the signal line and damaging the equipment.
Its main functions are:
Signal surge protectors can be divided into network signal surge protectors, monitoring signal surge protectors, control signal surge protectors, video signal surge protectors, tele signal surge protectors according to different types of protected lines, Explosion-proof signal surge protectors,s and many other types, each type has many models, parameters and different appearances.
SPD for Network / Data Line Surge Protector
Data line protector series are mainly used in TCP/IP communication networks to protect electrical and electronic equipment's signal line from the impact of lightning electromagnetic pulse, induced over-voltage, transient operation, and resonance overvoltage.
SPD for Audio Surge Protector
With a standard RJ11 interface, The audio signal lightning protection device is suitable for audio signal lightning protection of 1 to 4 pairs of dedicated communication lines and protection of trunk lines and internal lines of program-controlled exchanges.
SPD for Video Signal System
Come With BNC interface, video signal lightning protection device is suitable for monitoring systems and video-on-demand equivalents Axis communication equipment.
Industrial Control Line AI/AO Analog signal RS485 Protector
The control signal lightning protection device is designed to protect the control line system to protect the electrical and electronic equipment's signal line from the impact of the lightning electromagnetic pulse.
SPD for Ethernet Power System
The POE Ethernet series lightning protection device is a lightning protection device developed for POE network power supply equipment in accordance with the standard requirements of IEC61643-21, EN61643-11:2012, YD5075-98, and IEEE802.3AT.
SPD for Serial Signal System
The serial port signal lightning protection device is designed for communication network line not to be spoiled by lightning over-voltage, induce a voltage, and static discharge.
2 in 1 SPD for CCTV
2 in 1 monitor lightning arrester (power and network/ power and video/ power and control), is designed for a digital camera to protect the camera power and data line/power line/video line from the impulse of lightning electromagnetic pulse, induced over-voltage, operating over-voltage.
3 in 1 SPD for CCTV
3 in 1 monitoring surge protector is designed to protect the analog monitoring equipment ( power, data, control, video) from the damage of lightning electromagnetic pulse, induced over-voltage, operating over-voltage.
Explosion-Proof Signal Lightning Surge Protector
Explosion-proof signal lightning protector is designed for protecting instruments of 2line, 3 lines, 4 lines, from the impact of lightning electromagnetic pulse, induced over-voltage, transient operation and resonance over-voltage, transient operation, and resonance overvoltage.
