Power analyzer meters are popularly used in various industrial sectors in manufacturing as well as research and development divisions. The Vitrek PA900 Precision Harmonic Power Analyzer meter is one such equipment that is ergonomically designed to make it easy to use. The affordable pricing of this device allows you to purchase one without worrying too much about the power analyzer price in India. The device can be used as a high-performance measurement device that delivers consistent, multi-channel wideband results with an unprecedented accuracy. This high-performance measurement scheme allows you to measure energy easily even under tough payload conditions.


  • World Class Accuracy & Bandwidth
  • Easy-to-Use Touchscreen Operation
  • All the Data you need at a Price you can Afford
  • The Vitrek PA900 Harmonic Power Analyzer:
  • Precision + Ease of Use = Affordability

The best part about using the Vitrek PA900 Precision Harmonic Power Analyzer meter is its precise measurement scheme. Also, the incorporation of a colourful touchscreen interface at an affordable power analyzer price in India allows the user to ease the mode of operation by a significant amount. Accuracy as well as precision are the two of the strongest pillars on which the device operates. The device performs exceptionally well for the economical power analyzer price in India.

The Vitrek PA900 is one of the only devices that can easily produce over 100 accurate and precise readings every second. In addition, the device is capable enough to support a bandwidth reading of up to 5 MHz waveforms. No other power analyzer at this price in India has a capacity to tackle such a power factor. This power analyzer meter can easily produce results for high power, low phase angles as well as high crest factor loads. The high-performance device can tackle crest factor as high as 30:1 for a power measurement. The device fits squarely in the palm of your hands or if you prefer – at the tip of your finger.

The Best Solution for the Toughest Power Measurment 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.

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, 8 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.

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.

Scope View

Scope view offers waveform acquisition and analysis similar to a digital scope. Up to 6 signals can be displayed, each having user selectable scaling, offset and color. Timebase, trigger and trigger position are all user selectable. However, with amplitude accuracies as high as 0.03% – you are unlikely to find any other scope with this high level of precision.

Cycle View

The cycle view represents a single cycle of the voltage and or current periodic waveforms. The above waveforms represent a full 10V square wave in blue and a 50:1 zoomed in view in red. Since the user sets amplitude and scaling – the result is an almost unlimited ability to amplitude zoom to expose fine detail. The sampling is forced to be asynchronous to higher order harmonics which leads to an effective sampling rate of 384MSPS.

Vector Screen

A polar chart graphically displays the fundamental voltage and current vectors for the selected channel or VPA. For multi-phase VPAs, the inter-phase voltages and non-measured neutral phase vectors are displayed. The user may enable the display of and select the color of each vector up to a maximum of 10.

History Screen

The PA900 automatically maintains a continuous historical record of all non-harmonic measurement results and selected harmonics. Up to four user selectable parameters can be graphically displayed using the HISTORY screen. The user can display the entire recorded period up to 397 days or zoom in as far as 1/64th of the total span. This provides an almost unlimited ability to amplitude zoom and includes a cursor which may be moved throughout the period with a touch of the screen.

Standby Power Screen

The PA900 features built in standby power testing in accordance to EN50564:2011 (replaces IEC62301) which can be started with the press of a finger from the STBY POWER screen. All information is neatly organized onto a single screen for easy viewing and can just as easily be saved as an image file into a connected USB drive to add into any report. Various measurement methods laid out in EN50564:2011, minimum test time, and datalogging capability are all selectable. The PA900 also has the ability to perform standby power measurements independently in each configured VPA.

Modular Design means Flexibility

The PA900 uses a modular design approach to provide the performance you need at a price that meets your budget. A single PA900 chassis holds up to 4 Channels of power measurement in any combination of three different Channel types.

  • The S type Channel card provides economical, high performance power measurement with a basic 0.1% accuracy and enough bandwidth to handle waveforms up to 1.25 MHz.
  • The A type ultra-precision Channel card offers a 2 year accuracy rating of 0.03% of reading and bandwidth up to 1.25 MHz.
  • The W type Wideband Channel card performs precision power measurements on the toughest real world waveforms, with sampling speed fast enough to tame waveforms up to 5Mhz

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.
