The WT1800R is a high-performance power analyzer designed for precise evaluation of electrical power, efficiency and harmonic behaviour. With configurations from one to six power inputs, it supports simultaneous measurement of multi-phase converters, inverters and motor drive systems. High-resolution sampling and wide measurement bandwidth make it suitable for applications ranging from renewable energy systems to EV powertrains and industrial motor development.

  • Configure from 1 to 6 power input channels for single- and multi-phase power measurements
  • Simultaneous acquisition on up to 6 inputs at 2 MS/s with 16-bit resolution
  • Basic power accuracy of ±(0.05% of reading + 0.05% of range) at 50/60 Hz
  • Measurement bandwidth from DC and low-frequency signals up to 1 MHz for wideband power analysis
  • Harmonic analysis up to the 500th order of a 50/60 Hz fundamental, with up to 2 motor inputs for electrical and mechanical efficiency evaluation
  • 8.4-inch XGA display supporting numerical, waveform, vector and trend views for multi-channel analysis:
