The WT500 is a mid-range power analyzer for accurate single and three-phase power measurements in development, production and energy-efficiency testing. Available with up to three power input elements, it combines wide measurement ranges with fast data updates and simultaneous measurement of electrical parameters. Optional harmonic analysis extends its use to applications requiring evaluation of distorted or non-sinusoidal waveforms.

  • Available with 1, 2 or 3 power input elements for single and three-phase measurements
  • Basic power accuracy of ±(0.1% of reading + 0.1% of range)
  • Measurement bandwidth from DC and low-frequency signals up to 100 kHz
  • Direct voltage measurement up to 1000 V and current measurement up to 40 A, depending on the selected range
  • Data update rates as fast as 100 ms, with simultaneous voltage, current, power and energy measurements
  • Optional /G5 harmonic analysis enables simultaneous normal and harmonic measurements up to the 50th order, with numerical, waveform, vector and trend display
