iVS-3S

The iVS-3S is a self-contained, all-weather, digital instrument that measures and records voltage, current, and power on three channels. Simply plug it into any standard 200A 3-phase meter base with the revenue meter installed on top. The iVS-3S monitors RMS voltage, current, power factor, demand, phase angle, waveform capture, and harmonics to the 31st degree.
