Description
Overview
GAOTek IoT energy meter for three phase power monitoring 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.
