Automatic Analog Signal Surge Protector Over Voltage Protection Function

RJ11 control signal, lightning protector, automatic surge protector, analog signal, lightning protector.

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. it has three protection functions of over current, over voltage and clamping.

2. the low attenuation and return loss in the wide frequency range ensure that the lightning arrester does not affect the system performance.

3. the off state leakage current is extremely low, which does not affect the normal operation of the device.

Product specification

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 product is typically used for communication serial ports such as computers RS485 and RS422RS232. It is protected from damage caused by lightning induced voltage, grid voltage fluctuation, electrostatic discharge and impact voltage. It can be used for the protection of industrial control interconnected network, RS422/485 interface, special line, automatic control and instrument line, data line and telephone equipment, fax machine and so on. It can also be used for the protection of sensors and two instruments in the current ring.

Use of attention

1. "IN" connects the lead end, "OUT" connects the protected device (or system) end, "1" and "3" as a signal channel, "2" and "4" as a signal channel. When installing, the two ends must be laid separately, and not be tied together to prevent the two induction.

3. the lightning arrester is not required for long maintenance without longer maintenance. It only needs to be maintained by the system. In the course of use, the signal transmission is problem and the signal transmission is restored to normal after the surge protector is replaced, indicating that the surge protector has been damaged and needs to be repaired or replaced.
