Signal Surge Protection

TRSS-485 Control Signal Surge Protectors

  • Protect a pair of signal lines from lightning surge
  • DIN rail installation saves a lot of space
  • A variety of protection voltages are available, such as 5V 12V 24V 100V
  • The maximum discharge current is 10kA

Product introduction

The TRSS control signal lightning protector is used to protect sensitive high-speed communication network lines from damage caused by lightning induced voltage, powerinterference, electrostatic discharge, etc. The signal lightning protection device adopts multi-level protection circuit, selects world-famous components, and is manufactured by advanced production technology. It has the characteristics of large current capacity, low residual voltage level, sensitive response, stable performance, and reliable operation.

Installation and maintenance:

1. The lightning protection device is connected in series between the protected equipment and the signal channel.

2. The input terminal (IN) of the lightning arrester is connected to the signal channel, and the output terminal (OUT) is connected to the input terminal of the protected equipment, and cannot be reversed.

3. Reliably connect the ground wire of the lightning protection device with the ground wire of the lightning protection system.

4. This product does not require special maintenance. When the lightning protection device is suspected to be malfunctioning, the lightning protection device can be removed and thenchecked. If the system returns to normal after the system is restored to the state before use, the lightning protection device should be replaced.
