Vitrek WD Wideband Dual Current Channel Card

Overview

The Vitrek WD Wideband Dual Current Channel Card is an advanced measurement module for the PA900 Harmonic Power Analyzer. This precision channel card provides simultaneous voltage and current sampling for each of the two electrical channels, ensuring accurate phase correlation critical to power quality analysis. The wideband design handles complex real-world waveforms with fast sampling rates, making it ideal for measuring harmonics, transient disturbances, and non-sinusoidal power signals.

Key Features

• Wideband operation with 5MHz bandwidth for complex waveform capture
• 22-bit analog-to-digital sampling for high resolution
• Dual current shunt input option (up to 20Arms continuous, 150Apk inrush)
• Total 0.1% measurement accuracy on power calculations
• 600Vrms maximum continuous voltage input per channel
• Resolution down to 0.1µA on current shunt input
• Compatible with current output current transformers (CTs)
• Includes 4 color-coded 1.5 meter heavy-duty test leads
• NIST calibration certificate with uncertainties included

Modular Design & Flexibility

The PA900 mainframe accommodates up to four channel cards in any combination. The WD channel card can be paired with other channel types depending on measurement requirements. The S type Channel card provides economical 0.1% accuracy with 1MHz bandwidth. The A type ultra-precision card offers 0.03% accuracy with 1MHz bandwidth. The L type is optimized as a high-precision variant of the A type. This modular architecture allows customized configurations for specific power measurement applications.

Applications

• Power quality measurement and harmonic analysis
• Three-phase power system testing with simultaneous phase measurement
• Battery charging and power conversion testing
• Field power system commissioning and troubleshooting
• Automated power measurement systems via GPIB/USB connectivity
