The Vitrek PA900 Series Precision Multi-channel Harmonic Power Analyzer is actually three power analyzers in a single chassis with a single user interface. These are called Virtual Power Analyzers (VPA) or Channels. Channels may be configured in any one (or none) of the 3 VPAs. Each VPA may be configured for up to all channels installed and is independently configured for multi-channel wiring configuration, signal filtering, default measurement coupling, display results smoothing and significant digits, VA/VAR combine method and efficiency grouping. The Vitrek PA900 Series boasts an impressive array of precision power measurement capabilities, yet its color touchscreen user interface is refreshingly easy to use. The accuracy of the PA900 Series is truly world class-surpassing rival instruments costing triple the price. When it comes to speed and bandwidth, it tops the charts with 100 full precision readings per second and measurement bandwidths sufficient to handle 5MHz waveforms. For tackling tough power factor, low phase angle and high crest factor loads, it is certainly unbeatable. Offering full performance for crest factors as high as 30:1, the PA900 Series Precision Multi-channel Harmonic Power Analyzer places the advantage of superior power measurement capability.
