TRSS-485 control signal surge protection device
Model: TRSS-485
Color: white / red
Verification: CE
product description
The control signal lightning arrester is the lightning protection measure adopted by Zhejiang Thor Electric Co., Ltd. for independent research and development and production for signal circuit protection. It is used to protect various types of crimping control signal equipment sensitive to electromagnetic interference. It is used to protect sensitive control signal lines from damage caused by lightning overvoltage, induced overvoltage, overcurrent, electrostatic discharge, etc. Compared with the popular 485 products on the market, this has more powerful shielding performance.

Product Features
1. With overcurrent, overvoltage, clamp triple protection.
2. When a lightning strike is invaded, there is no need to suspend the power equipment, and it will not affect the normal equipment operation.
3. Low attenuation and return loss in the wide frequency range to ensure that the lightning arrester does not affect system performance.
4. Using ultra-low capacitance design, good signal transmission performance.
5. Some more powerful shielding performance than the general RS485.
Product working principle
TRSS-485 signal surge protector is connected in series with the front end of the protected device. When the transmission line is subjected to induced lightning and other transient overvoltage surges, the inrush current is discharged to the earth through the protection branch of the surge protector, and the output is output. The voltage is clamped to the voltage range allowed by the device, thus ensuring the safety of the operating equipment.
Use attention
1 signal lightning arrester can be installed in the LPZ0-1 area or directly connected in series to the front end of the protected equipment (or system). The closer it is to the protected equipment (or system), the better.
2. The control signal lightning arrester can be easily fixed on the 35mm electrical rail.
3. “IN” is connected to the lead end, “OUT” is connected to the protected device (or system), “1” and “3 are one signal channel, and “2” and “4” are one signal channel. Must be laid separately, not bundled together to prevent secondary induction.
Company Profile
Zhejiang Thor Electric Co., Ltd is committed to meeting the requirements of the European Union’s Waste Electrical and Electronic Equipment (WEEE) directive. This directive requires producers of electrical and electronic equipment to finance the take-back for re-use or recycling of their products placed on the EU market after 2005.
