SMC - Surge and Lightning Monitoring device

SETREON has dedicated its research activities to lightning and surges qualification. This new range of products aims at helping our customer to understand the origin of surges, their parameters and impact on equipment.
It involves diagnostic of metal oxide based surge arresters (MOR,TLA, MOA) in service, record peak currents, historical data, number of events, cumulative charges discharged by equipment.
It allows ageing and problems qualification to reach higher accuracy in order to optimize reliability and expenditure.
With a communication range of 2.5km LoRaWan standards allows the user have a safe and remote connection.
SM Series Surge Monitoring can be installed easily on ground conductors.Thanks to its IP65, housing, rugged materials and self power, the SM Series suitable for outdoors.
Power supply is ensured through supercap cell and solar panels. Optional DC power supply can also be arranged.
Key features
