PA920 Ultra-High Accuracy Multi-Channel Harmonic Power Analyzer

PA920

Power Accuracy 0.024%
Bandwidth 5 MHz
Harmonics Up to 500
Readings 100 full-precision per second
Crest Factor: Up to 100 1
Channels Up to 4 (modular channel cards)

The PA920 is Vitrek’s most accurate power analyser: 0.024% power accuracy on all channels, 5 MHz bandwidth, and 500-harmonic analysis in a modular, touchscreen-operated platform. For LED lighting, EV inverters, solar systems, PWM motor drives, and any application where measurement error has consequences.

The PA920 delivers 100 full-precision readings per second across a dynamic range capable of handling high crest factors up to 100:1 and low power factor loads, conditions that expose measurement errors in less capable instruments. Built-in waveform visualisation, scope view, cycle view, vector view, and a continuous history screen give engineers the full picture of what’s happening in their power circuit.

Modular architecture: up to 4 channel cards per mainframe, configurable from 7 card types. Ultra-Precision (UT/UX) cards deliver the 0.024% accuracy specification. High-Bandwidth (BT/BX) cards extend frequency coverage. Kilovolt (KT/KX) cards support up to 1.6kVrms continuous. A Motor Transducer (MT) card in slot 4 adds motor efficiency measurement. Virtual Power Analysers (VPAs) support 3-phase and efficiency grouping measurements across channels.

Built-in data logger stores 16 data points to USB or internal memory. Ethernet, RS232, and USB interfaces standard. CE certified, made in USA, 2-year warranty.

Overview

The PA920 is the PA-series flagship: 0.024% accuracy, 5 MHz bandwidth, and 500-harmonic analysis on a modular platform that can be configured from a single-channel lab instrument to a 4-channel multi-phase power measurement system. The choice when measurement accuracy is the deciding factor.
