Part No.

SEN450

Wireless 3-phase current detector is used to detect 3-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 battery and obtains the load AC current value through the current transformer. The device adopts the split-core current transformer, which can be conveniently connected to the measuring device.

Application

- Indoor current detecting devices for homes, hotels, office buildings, shopping malls, etc.

- Smart city

- Thermal system equipment
