The Netvox R718N163 is a LoRa‑WAN compatible wireless single‑phase current detector with low power consumption and detailed electrical specifications.
The Netvox R718N163 wireless single‑phase current detector measures AC line current via an external current transformer and reports the data over LoRaWAN to a gateway for cloud‑based monitoring. It is battery‑powered, supports long‑term deployment, and can be integrated with third‑party IoT platforms.
Key features include a SX1276 LoRa module, dual ER14505 Li‑ion batteries (3.6 V, 2400 mAh each) with an estimated 5‑year life, IP53/IP30 protection, built‑in antenna, and configurable parameters via third‑party software. Electrical specifications cover a measurement range of 5 A–630 A, ±1 % accuracy, 1 mA resolution, and RF performance up to 19 dBm output power. This manual is written in Chinese.
