Home lightning protection signal protector, control signal, lightning protector, RS485 lightning arrester.
Brief introduction
The control signal lightning arrester is a lightning protection measure developed by Zhejiang tohr Electric Co., Ltd., which is independently developed for signal circuit protection. It is used to protect all kinds of voltage connected control signal devices sensitive to electromagnetic interference, which can protect the sensitive control signal lines from the damage caused by lightning overvoltage, induced overvoltage, overcurrent, electrostatic discharge and so on, and effectively protect the equipment.
Product features
1. low insertion loss (less than 0.5dB).
2. The transmission rate is high and the frequency range is large.
3. the reaction speed is fast.

Working principle of product
The control signal surge protector is connected to the front end of the protected equipment. When the transmission line is impacted by the inductive thunder and other transient overvoltage, the impact current is discharged to the earth through the protection branch of the surge protector, and the output voltage is placed in the allowable voltage range of the equipment, thus ensuring the safety of the operating equipment.
Use of attention
1. lightning arrester grounding with the shortest possible line connection. The protector grounding adopts terminal grounding mode, and the grounding wire must be connected to the lightning protection ground wire (or the enclosure of the protected equipment). The shielding wire of signal can be directly connected to the grounding terminal.
2. the lightning arrester is not required for long-term maintenance without longer maintenance. It only needs the routine maintenance of the system. In the process of use, the signal transmission is problem, the signal transmission is restored to normal after the surge protector is replaced, indicating that the surge protector has been damaged, and it needs to be repaired or replaced.
3. please recognize the interface and the way of connection.
