Product Description
ADW series rail type multi-loop power meters are mainly used for measuring the full electric parameters of multiple three-phase circuits, up to four three-phase loop current inputs can be connected simultaneously. It can measure voltage and current, power, power factor, phase angle, unbalance, harmonic and other parameters.
