Vitrek PA903 Power Analyzer

Overview

Vitrek PA903 is a modular, three-channel power analyzer designed for multi-channel, high-precision power and energy measurements. Part of the PA900 series platform, it delivers exceptional measurement accuracy with an industry-leading 1ppm noise floor—significantly lower than competitive units which typically exhibit 300ppm or more. The PA903 features a large, high-resolution color touchscreen display with intuitive interface, making it ideal for complex power measurement applications including three-phase systems and efficiency testing.

Key Features

• Three-channel configuration with expandable design (up to 4 total channels available)
• Industry-leading 1ppm noise floor for superior measurement accuracy
• High-precision measurement: up to 0.03% (A-type), 0.1% (S-type and W-type)
• Bandwidth options: 1 MHz (S and A types), 5 MHz (W-type)
• 384 MSPS effective sampling rate for periodic signal analysis
• Up to 500 harmonic calculations at 400 Hz (meets Airbus avionics criteria)
• Measurement resolution: 24-bit (A-type) or 22-bit (S and W types)
