DC, 0.5 Hz to 150 kHz, 3-phase 4-wire, High Precision Power Analyzer for Motor and Inverter Efficiency Analysis


PW3390: D/A output and motor analysis function is specified by the order code.

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 3390-10 is our most precise power analyzer, featuring a broad range for measuring electrical power from DC to inverter frequencies, providing four input channels to support single- and three-phase inverter motor system measurements.

Key Features

  • Super precise ±0.1% accuracy model to meet the demanding needs of today
  • Switch from one range to another and still maintain the same ±0.1% accuracy on all ranges
  • Guaranteed accuracy period is extended another 6 months from the basic Model 3390 (other functions remain the same)
  • Advanced motor analysis functions (measures the electric angle and supports vector control)
  • High-speed harmonic analysis function (50 ms data refresh rate)
  • Noise analysis function for inverters (using FFT analysis technology)
  • Inverter power measurement with the convenience of clamp on sensors
