Lightning arrester microampere (μ A) leakage current coil

The lightning arrester varistor (SPD) micro ampere level (A) leakage current coil is a high-precision and easy to install opening and closing precision coil developed over the years based on the lightning protection industry. It is also a product independently developed by Keyu IoT, with relatively complete functions

lightning protectionThe micro ampere (μ A) leakage current coil of the varistor (SPD) has been developed for many years based on the lightning protection industry. It is a high-precision and easy to install opening and closing precision coilKeyu IoTIndependently developed products with relatively complete functions; Comprehensive improvement in product performance (mainly referring to easier installation and higher precision);
This product needs to be used in conjunction with lightning protection monitoring terminalsThusaccuratemonitorThe small current leaked from the surge protector (SPD) to the ground; Further through lightning protectionThe data collection host transmits the monitored data information to the indoor environment through Ethernet RJ45 network or wireless communication mode (433MHz or other methods)The signal processing host displays the collected data information through local display or computer screen after signal processing is completed. User data lightning situationWhen maintaining the equipment, the information on the display screen can be used to determine whether the monitoring point has been struck by lightning. If it has been struck by lightning, real-time data on the leakage current of the sub sensitive resistor can be viewedLightning strike time, number of lightning strikes, etc.Monitor the working status of indoor SPDs, check if they are working properly, and accurately locate damaged or abnormal SPDs.Outdoor monitoring and indoor monitoring form a system with a simple and easy to understand interface, which can be operated on a PC platform orIndependent operating system;

Installation requirements:
(1) Installation must be carried out by a professional certified electrician, and live operation is strictly prohibited.
(2) The normal working conditions of the intelligent lightning protection monitor must be met, with a power supply voltage of AC 220V from the mains, and the power supply voltage cannot exceed that of the intelligent oneLightning protection monitorThe maximum continuous operating voltage and working environment must meet the requirements of the product performance table parameters.
（3）Intelligent lightning protectionMonitor installation method: 35mm DIN standard rail installation, in compliance with DIN EN60715 standard.
(4) The main purpose of this product is to monitor the status of surge protectors (SPDs), which are usually installed indoors and located near the SPDs.
(5) The specifications of the power input and output lines, as well as the ground wire, should meet the regulatory requirements, and the wiring should be short and thick, ensuring that the grounding resistance is less than 4 ohms.
(6) Connect the power and communication wires according to their colors, and do not connect them incorrectly.
(7) Before installing the product, the appearance must be checked. If damage or errors are detected, installation cannot proceed
(8) Disassembling or modifying the product renders the warranty invalid
