Scenario Preset
(1)There are 10 Area which are far from each other or are hard for RS485 wiring. (2)Each Area has 1 load 3-phase powered by 1 circuit 3-phase that needed to be monitored. (3)Each circuit are with rated voltage of 400Vac L-L&230Vac L-N, and with rated current of 150A AC. (4)Circuits’ current are carried by cable, of which the size was suitatble for φ24mm aperture. (diameter) (5)For each monitoring circuit, we will install 1* ADW300-4GHW/C Wireless 4G 3-phase Energy Meter paired with 3* AKH-0.66/K K-φ24 150/5 for current input.Devices Deployment Plan
Communication Structure&Logic
(1)4G Communication could be served as one of the final data upstream methods by sending the data to cloud server deployed in Internet so that Acrel IoT System could be interact with these data collected by bottom metering devices like Energy Meter (2)ADW300-4GHW/C Wireless 4G 3-phase Energy Meter has a built-in 4G communication module which allow it to directly send data to local 4G telecom tower through 4G signal based on MQTT and MODBUS-TCP protocol without using a extra 4G IoT Gateway. (3)Each ADW300-4GHW/C has a 4G card tray for installing the 4G sim card which could be bought from your local 4G service provider. (4)ADW300-4GHW/C also have a RS485 communication normally used for devices adjustment with Acrel ADW300 adjustment softare.
