Hioki PW3390 power analyser

The Hioki PW3390 power analyser is suited to mains power frequency and power electronics, high-frequency power measurements such as solar and wind farms, variable speed drives and electric vehicles. The product captures input waveforms with 500 kS/s high-speed sampling and a 16-bit A/D converter performing period detection, wideband power analysis, harmonic analysis, waveform analysis and noise analysis.

High-speed simultaneous calculation processing enables both precise measurements and a 50 ms data refresh rate. There are four independent input channels with ±0.04% basic accuracy for power providing 200 kHz measurement band and flat amplitude and phase characteristics. A zero-crossing filter detects the fundamental frequency for harmonics analysis in the range of 0.5 Hz to 5 kHz. A wide range of current clamps and Rogowski coils, and a current input module for line currents to 50 A, provide wide measurement flexibility.
