Key Benefits

And speaking of flexibility, each of the above Channel cards is available with your choice of 3 different current input options. The D current input option uses an auto-ranging Dual Shunt system to deliver precision current measurement from as low as 0.1micro-amp resolution on the 1 amp range up to 20 amps rms on the high range. For higher current measurements, the H current input option operates from 10 micro-amp resolution up to 30 amps rms. The X input current option is designed to provide optimum compatibility with a wide range of external shunts and current transducers. Vitrek makes it easy for you to configure a harmonic power analyzer that is perfect for your application.

Power Data Screen

The power data screen, available with one touch, displays V, A, W, VA, VAR and PF data for any selected channel or group of channels known as a Virtual Power Analyzer™ (VPA). Up to three different VPAs can exist in in a single PA900. In addition to the primary data, peak readings, phase, CF and other parameters are also available. Integrated data results (WHr) can also be controlled and viewed from the power data screen. For users with unique data requirements, custom data screens can be built with a spreadsheet application and downloaded to the PA900 via interface or USB drive.

Harmonics Screen

To meet advanced power harmonics requirements, the PA900 displays up to 500 harmonics even at aviation power frequencies. The chart can be set to show linear, relative linear, logarithmic or relative logarithmic amplitudes Additionally, eight harmonics can be selected for numeric display of amplitude and phase by touching the harmonic bar of interest. The user may also import harmonic limits, which
when enabled will show out of tolerance harmonics in red above the limit line.

The Best Solution for the Toughest Power Measurement Applications

Energy is one of our most precious resources. 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 PA900 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.
