EM2840 Lightning Strike Current Online Detector is also known as intelligent SPD lightning monitoring module. This detector can monitor SPD alarm actions and alarm action time, lightning strike times, lightning strike amplitude, and SPD life warning in real time and accurately, and transmits real-time data monitored by the intelligent SPD lightning monitoring module to the monitoring server software (user-supplied) via RS485 bus.A2840 Lightning Current Online Monitor consists of host and flexible coil. The host adopts standard 35mm DIN rail installing. The flexible coil is light and soft for extremely easy installation, and its diameter can be customized.
This detector can monitor and collect SPD alarm signals, monitor the amplitude, polarity and occurrence time of lightning current. Equipped with a digital tube display to show the latest lightning strike counts and degradation alarm signals in real time. This detector has a life warning function to indicate life through the LIFE indicator, and transmits collected data to the upper computer via RS485 bus. The SPD alarm function is suitable for SPD devices with dry contact output, enabling timely and rapid monitoring of SPD operating status and effective early warning.
SPD (Surge Protective Device) is also known as surge protector and lightning arrester, is an electronic device used to limit transient overvoltage (surge) in circuits and discharge excess surge current, thereby protecting downstream electronic equipment and power equipment from surge damage. It is a core protection component for lightning protection and electromagnetic compatibility (EMC) in power systems, communication systems, industrial control and civil electrical appliances (such as computers and routers).METER is a high-end brand of. All products are manufactured by, which also provides technical support and after-sales service.
