What is the Lightning Current Monitor (Indoor)?

Lightning Current Monitor (Indoor) is a lightning current peak recording device developed by FEXLINK for distribution cabinets, equipment rooms and other indoor scenarios. It uses a Rogowski coil sensor to record lightning strike time, polarity, peak value, waveform and other parameters, with 100 sets of cyclic data storage and 35mm DIN rail mounting.

What is the range and accuracy of the Lightning Current Monitor (Indoor)?

Range is 1kA~120kA, accuracy ±5%, compatible with 8/20μs and 10/350μs standard lightning current waveforms, accurately capturing direct and induced lightning events.

What communication methods does the Lightning Current Monitor (Indoor) support?

Supports RS485, Zigbee, Ethernet and 4G communication, flexibly connectable to FEXCloud platform or local monitoring systems for remote lightning event alarms and historical traceback.
