Hioki benchtop power meters and power analysers 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 analyser for measuring electrical power from DC to inverter frequencies, providing four input channels to support single- and three-phase inverter motor systems up to 4000A 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.


Delivering High Accuracy and Mobility in One Single Device

The Hioki PW3390 Power Analyser offers ±0.04% ±0.05% f.s. power accuracy, the top of its class.

With a 200kHz measurement bandwidth and flat amplitude and phase characteristics up to high frequencies, as well as a powerful phase shift correction function that maximizes the power of its original current sensors, the PW3390 can now be utilised by researchers and developers to high frequency, low power factor power with absolutely accuracy.

Apply the PW3390 and Hioki current sensors to power conversion efficiency evaluations and the analysis and harmonic studies of EV and HEV inverter motors.



Using the Hioki PW3390 to Evaluate Vehicle Fuel Consumption Performance according to the Worldwide Harmonized Light vehicles Test Procedure (WLTP)

The Hioki PW3390 Power Analyser is extremely effective in evaluating the fuel performance of automobiles, including in accordance with the Worldwide Harmonised Light vehicles Test Procedure (WLTP).

Pair with Hioki high accuracy current clamp sensors to achieve high accuracy measurements even within hot engine compartments.
