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 beflexibly installed in the distribution box to realize the measurement, statistics and analysis of individual electric energy in different regions and loads.


It can measure all power parameters including voltage U, current I, active power P, reactive power Q, apparent power S, power factor PF, phase angle of voltage and current Φ, voltage unbalance, current unbalance, frequency F, 2-31st fractional harmonics,odd and even total harmonics and total harmonics. Voltage U reserved 1 decimal, frequency F reserved 2 decimal, current I reserved 3 decimal, power P reserved 4 decimal, phase angle Φ reserved 2 decimal, unbalance reserved 2 decimal. Supporting 4-channel temperature measurement and residual current monitoring.
