With an extended measurement range from micro-amps to hundreds of amps and milli-volts to kilovolts, the Lexcom PA2801 and PA2802 are ideal power analyzers and harmonic analyzers for appliance testing, standby power or Energy Star conformance testing. High speed digitization of voltage and current allows accurate power analysis of both clean and distorted power signals. Our harmonics & power analyzer’s graphical display includes numeric results, voltage and current waveform plots along with settings. Measurements can be displayed or read on our power analyzer via the communication ports; RS-232, GPIB, USB, and Ethernet, or sent directly at full resolution to a USB printer.

PA2801 and PA2802 Harmonics & Power Analyzer Features:

  • Accurate with all AC/DC waveform types
  • High performance-to-cost ratio
  • Measures, W, VA, VAr, V, A, PF crest factors and harmonics
  • Base accuracy <0.08%. Current and voltage accuracies specified to less than 1mArms and 1Vrms respectively (<0.2%)
  • 2000Vpk and 150Apk measurable internally (external current probe capable)
  • Integrated line switch and inrush waveforms
  • Graphics display shows numerical results, waveforms, bar graphs, startup & history charts with zoom & scroll features
  • Wiring loss and voltage burden compensation
  • Harmonic Analysis
  • DC charge and discharge measurements
  • Frequency Range: DC and 20mHz – 200kHz
  • Communications ports include USB, GPIB, and RS-232 standard, plus optional Ethernet*
  • USB Flash drive support for data logging*
  • Provides PASS/FAIL tests to user limits*

*Planned Power Analyzer features coming soon
