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. The surge protector is mainly used for industrial control system data control signal, communication line, telemetry signal and remote control signal. It is applied to the 1-2 and 2-3 areas of the lightning protection area. Prevent direct lightning and overvoltage damage to equipment.

Product specification

1. Working voltage:24V

2. Max continuous operating voltage(UC):30V

3. Voltage protective level(UP):<60V

4. Nominal discharge current(IN):10KA

5. Response time(NS): ≤10

6. Characteristic impedance: 75Ω

7. Insertion loss: ≤0.1dB

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. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.

2. before the protector is connected to the system, check the grounding resistance of the grounding grid first. It should comply with the specification requirements.

3. grounding lines should be short, thick and straight, so as to reduce the influence of distributed inductors on the ability of lightning electromagnetic pulse.

Product features

1. using ultra low capacitance design, the signal transmission characteristic is good.

2. it has self recovery function and provides multiple protection under lightning prone environment.

3. advanced production process and beautiful appearance
