AEW100 wireless meter is mainly used to measure three-phase active energy of low-voltage network. It has RS485 communication and 470MHz wireless communication function, which is convenient for users to monitor, collect and manage electricity consumption. It can be flexibly installed in the distribution box to realize sub-item electric energy measurement, statistics and analysis for different areas and different loads.
