Description

Industry’s Easiest-To-Use Power Analyzer  – Vitrek’s PA910 Series power analyzers are the industry’s easiest-to-use power analyzer. Equipped with a full color touchscreen, the PA910 enables users to quickly and easily setup configurations, custom screens and interface commands.

Maximize Flexibility – The PA910 ower analyzer offers expanded power analysis options. The PA910 provides improved accuracy to 0.045% power for all channels and improved voltage and current self-heating adders over those of the PA900 series. In addition, the PA910 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 PA910 power analyzers are unbeatable. Offering full performance for crest factors as high as 100:1, the PA910 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 PA9xx 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 PA910 offers 8 available channel combinations to meet your power analysis needs.

Harmonics Screen

To meet advanced power harmonics requirements, the PA910 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 PA910. 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 PA910 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 PA910 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 PA910 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.
