Netvox‘s long-range, long-life wireless split core LoRaWAN® 3 phase 75A current meter is used to measure the true values of 2 or 3 phase mains AC current.

The data outputs are fed to a centralised monitoring system via the LoRaWAN® protocol to allow remote access to the data and creation of reports.


  • LoRaWAN® Class A compatible
  • Requires 2 x ER14505 AA Lithum 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 10 years (determined by sensor reporting frequency and other variables)

We can supply third-party online wireless sensor monitoring and notification system to view data and set alerts via SMS text and email.

Ask us about our zero-touch provisioning service, this sensor can be supplied pre-configured and ready to go.
