Key Benefits

Industry’s Most Accurate Power Analyzer – Vitrek’s PA920 Series power analyzers are the industry’s most powerful and accurate power analyzer.  The PA920 offers 0.024% power accuracy, the fastest available on the market today. All Vitrek power analyzers are easy to use with a full color touchscreen enabling users to quickly and easily setup configurations, custom screens and interface commands.
 
Maximize Flexibility – The PA920 power analyzers offer expanded power analysis options. The PA920 offers 0.024% power for all channels and improved voltage and current self-heating adders over those of other power analyzers. In addition, the PA920 provides easy channel selection for the user while offering 100 full precision readings per second and measurement bandwidths sufficient to handle 5 MHz waveforms.
 
Maximum Results – For tackling tough power factor, low phase angle and high crest factor loads, the PA920 power analyzers are unbeatable. Offering full performance for crest factors as high as 100:1, the PA9xx series provides superior power measurement capabilities for the toughest power measurement applications.
 
Maximum Performance in a Variety of Applications – Design engineers are under constant pressure to increase efficiency and reduce excess product power consumption down to the last mW. Challenging programs like LED and HID lighting, solar panel energy output, efficiency testing on inverters and PWM motor drive systems on electric vehicles—all require fast, precise, reliable power measurement. The unequalled performance of the Vitrek PA910/920 gives you the competitive advantage—the ability to accurately capture the waveforms and power data you need to squeeze the last drop of extra energy out of your project.
 
Modular Design = Maximum Flexibility – The PA920 Series Power Analyzers are available in both pre-configured models or can be purchased in a modular package to provide the performance you need at a price that meets your budget. A single PA920 offers 8 available channel combinations to meet your power analysis needs.
