R718N17D Wireless Single-Phase Current Meter with 1 x 75A Clamp-On CT (DC-powered)

   

The NETVOX wireless single-phase current meter is used to detect single-phase electrical input current. The device is compatible with the LoRaWAN protocol and integrates a chip module that conforms to the LoRaWAN wireless protocol to display the collected data in the gateway. The device obtains the load AC current value through the current transformer, which can be conveniently connected to the measured device.
