Netvox R718N37 – LoRaWAN Split Core CT 3-Phase Current Meter 3 x 75A

Netvox’s long-range, long-life wireless 3-phase 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.

Features

  • 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)
  • Over-the-air updates (future)
  • Third-Party online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email (optional)
