All the Data you need at a Price you can Afford
Harmonics
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 a 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.
Data all in one
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).
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. 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
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
Represents a single cycle of the voltage and or current periodic waveforms. The 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
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
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
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 to any report. Various measurement methods laid out in EN50564:2011, minimum test time, and data logging 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.
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 0.1 micro-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.
