Ankrui Liu Qiuxia

Multi terminal real-time access/ADW instrument allows data viewing anytime, anywhereMainly used for measuring three-phase active energy in low-voltage networks, it has the advantages of small size, high accuracy, and rich functions. It also has multiple communication options, including RS485 communication and wireless communication methods such as Lora, NB, 4G, wifi, etc. It also adds a current sampling mode for external transformers, making it convenient for users to install and use in different situations. It can be flexibly installed in the distribution box to meet the needs of sub item energy metering, operation and maintenance supervision, or power monitoring for different areas and loads.
