Netvox R718N3 – LoRaWAN Solid Core CT 3-Phase Current Meter 3 x 60A

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. Please note if the clip on version is required the part number is N718N37.

Features

  • Wireless range of up to 10 km (depending on environment)
  • Requires 2 x ER14505 AA lithium batteries
  • LoRaWAN Class A compatible
  • 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)
