CCSC Energy
1 / 5
ADW300 wireless meter is mainly used to measure three-phase active power in low-voltage network. It has the functions of RS485 communication and 470MHz wireless communication. It is convenient for users to monitor, collect and manage electricity. It can be flexibly installed in the distribution box to realize the measurement, statistics and analysis of individual electric energy in different regions and loads.
