Acrel Three Phase DIN Rail Power Energy Kwh Meter Wireless Transmission 4G WiFi Lora High Accuracy RS485 Adw300

Product Description

Descaiption
ADW300 Wireless Metering Meter is mainly used to metering three phase active energy on low voltage network. The product boasts of advantages including compact size, high precision, rich features. According to different requirements, there are many communications functions like RS485 communication, WIFI, NB, 4G, adding the new current sampling mode using external transformer. It can be flexibly installed in the distribution box to achieve sub-item electric energy metering, operation and maintenance supervision or power monitoring requirements for different regions and different loads.
