The R718N315 NETVOX wireless three-phase current detector is used to detect three-phase electrical input current. The device is compatible with the LoRaWAN protocol, and integrates a chip module that conforms to the LoRaWAN wireless protocol, and joins the gateway to display the collected data in the gateway.The device is powered by a battery and receives AC current through a current transformer.

This device adopts open-loop current transformer, which can be easily connected to the device to be tested. The A phase line, the B phase line and the C phase line of the three-phase electric power are respectively connected to the corresponding current transformers.


Example Applications

  • Smart current detection equipment in the city such as home or business
  • Thermal system equipment
