Industrial RS485 signal protector, control signal, surge protector, arrester 5V12V24V.
Product Details
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. The control signal lightning arrester is mainly used for lightning (overvoltage) protection along the low voltage control signal circuit, which is widely used in the financial system, telecommunication system, transportation system, petrochemical industrial control system, such as various data transmission lines, monitoring and control lines, instrument signal lines and so on.

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.
Product features
1. core components are strictly screened and their performance is superior.
2. Design of low capacitance and inductance and superior transmission performance
3. it has self recovery function and provides multiple protection under lightning prone environment.
Use of attention
1. identify the input / output interface identifier of the lightning protector, input the external line and output the device.
2. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.
3. the grounding of industrial control signal lightning arrester should be connected to the grounding grid through electronic switches.
Company profile
Thor is following the international quality system standards, is ISO 9001 certified and our technical standards are in line with GB18802.1-2011/IEC61643-1.
