R718N115E Wireless Single-Phase Current Meter with 1 x Detachable 150A Clamp-On CT

   

The Netvox wireless single-phase current detector 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 is powered by batteries and obtains the load AC current value through the current transformer. The device adopts the clamp-on current transformer, which can be conveniently connected to the measuring device.
