Netvox R718N17 LoRaWAN 75A Current Meter Split Core 1-Phase

The Netvox LoRaWAN 75A current meter is designed to detect single phase electrical current via a split core current transformer which can be conveniently retrofitted to the measuring device.

The energy data is transmitted in accordance with a pre-set schedule via the LoRaWAN gateway which can then be analysed ready for the appropriate action to be taken.

Netvox LoRaWAN 75A Current Meter Clamp On Sensor


  • LoRaWAN Class A compatible
  • Requires 2 x ER14505 AA Lithium batteries
  • Frequency Hopping Spread Spectrum (FHSS)
  • Improved interference immunity
  • Improved power management for longer battery life
  • Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data messages)
  • Battery Life of up to 5 years (determined by sensor reporting frequency and other variables)
