Smart Lightning Strikes Counter TDZ-LJQ

Name: Smart Lightning Strikes Counter TDZ-LJQ
Brand: Shenzhen Techwin Lightning Technologies Co., Ltd.

With the increasing automation of electronic and electrical systems, electromagnetic pulse interference (such as lightning strikes) can easily cause equipment damage. It is difficult to detect the failure of traditional surge protectors (SPDs) in time, which poses a safety hazard.

This product can monitor the SPD status in real time, including operating conditions, switch status, lightning strike records (number of times, time), etc., and save alarm and lightning strike data. Combined with special software and hardware (such as dynamic ring RTU), an intelligent lightning protection monitoring system can be built to achieve remote data upload and centralized monitoring. It is suitable for decentralized places such as railways, wind power, and airports, effectively reducing protection blind spots and improving equipment safety.

Feature of Smart Lightning Strikes Counter TDZ-LJQ

Small size: This product is a rail-mounted instrument that can be easily integrated into lightning protection boxes, lightning protection cabinets, distribution boxes, distribution cabinets, and network cabinets without changing the original product dimensions and layout.
Easy to install: All interfaces are plug-in terminals, which can be quickly installed and maintained.
Interface types: SPD/SCB remote signal collection, NTC temperature (multiplexing port, when this function is selected, one remote signal port will be missing), PE access status collection, lightning strike counting, ambient temperature and humidity functions, etc.
Support local button modification of instrument RS485 address.
Communication method: The product is equipped with RS485 interface as standard, which is convenient for data upload and cascade expansion; other communication methods such as Ethernet, Lora, and 4G can also be realized through expansion.
Strong anti-interference ability: The serial port is equipped with surge protection circuit, and the acquisition port is designed with photoelectric isolation circuit to ensure that the product is not interfered by surge and electromagnetic waves to the greatest extent.
