Hioki benchtop power meters and power analyzers are best in class power measuring instruments for measuring single to three-phase lines with a high degree of precision and accuracy. The PW3390 is a high-precision, broad-range power analyzer for measuring electrical power from DC to inverter frequencies, providing four input channels to support single- and three-phase inverter motor systems up to 4000 A AC/DC with superior accuracy.
High-accuracy, high-speed calculation of transient-state power in 50 ms; harmonic analysis; display of instantaneous waveforms; noise analysis; and simultaneous parallel calculation of all parameters, including efficiency loss
