ADW series din rail energy meter is mainly used for metering three phase active energy on low voltage network or medium voltage. There are RS485,4G,NB-IoT,WIFI communication way in order to help customers check, get and manage the value of energy consumption remotely.
It can be installed in distribution box flexibly, achieving the different demand of measurement and statistics of distribution on different areas and different loading. Besides, it can be equipped with other modules such as temperature measurement and residual current measurement.
It also could work with our IoT platform to help customers to check all parameters remotely.（See More）

Details
-
Communication via 4G or WIFI
ADW300 with built-in 4G or WIFI module could send the data to our IoT platform or third-part platform directly.1 -
Communication via Lora
ADW300 with built-in Lora module could send the data to our gateway AWT100 series, and AWT100 series could collect data of maxium 20 units of ADW300. Then AWT100 upload the data via 4G or WIFI.2
