Harmonics

The Vitrek PA900 displays up to 500 harmonics even at aviation power frequencies. Harmonics amplitude can be set to display in linear, relative linear, logarithmic, or relative logarithmic scales. Touching the harmonic bar on the screen allows selection of up to 8 harmonics for digital display of amplitude and phase. Harmonic limits can also be imported, and any out-of-limit harmonics will be highlighted.

 

Power Data

Quickly display V, A, W, VA, VAR, and PF metrics for any selected channel or grouping within the Virtual Power Analyzer (VPA). Additional data such as peak values, phase, crest factor, and results (WHr) can also be viewed. For customized data presentations, create personalized display screens using spreadsheet programs and upload them via USB or interface.

 

Scope View (Oscilloscope Simulation)

Offers oscilloscope-like waveform capture and analysis. Up to six signals can be displayed simultaneously, with scalable, offset, and color options for each signal. Timebase, triggering, and trigger position settings are fully adjustable. With measurement accuracy as high as 0.03%, it surpasses typical oscilloscope capabilities.

 

Cycle View  (Per Cycle Display)

Displays voltage and/or current waveforms of the current cycle. Example waveforms illustrate snapshots of a 10V blue square wave and a 50:1 red zoomed-in view. Amplitude and zoom settings are highly adjustable, showcasing minute details with a sampling rate reaching 384 MSPS.

 

Vector (Polar Chart)

Displays vector representation of voltage and current for selected channels or VPA configurations on a polar chart. For multi-phase VPAs, interphase voltages and unmeasured neutral vectors are displayed. Users can enable up to 10 vectors and select color options for each.

 

History Records

Automatically retains all non-harmonic measurement results and selected harmonic data in continuous history. The HISTORY screen can graph up to four selected parameters, covering recording periods up to 397 days or zooming into 1/64 of the full range. Touchscreen controls facilitate cursor movement through the data.

 

Standby Power Measurement

The Vitrek PA900 is equipped with built-in standby power testing compliant with EN50564:2011 (formerly IEC62301). Press the STBY POWER button to initiate a measurement. All data is clearly displayed on a single screen for easy viewing and can be saved as image files to a connected USB device for reporting purposes. EN50564:2011 measurement methods, minimum test durations, and data logging are fully configurable. The PA900 can independently perform standby power measurements on each configured VPA.

 

Highly Flexible Modular Design

The Vitrek PA900 features a modular measurement design, balancing performance capabilities with budget constraints. The main unit supports four module slots, allowing combination of various channel configurations. Flexible design includes variable input current selection, with different current input ranges for each channel card option.

X Module: Optimized for external shunt and current sensor connections.
