Working Principle:
The module utilizes a 20-bit Delta-Sigma A/D converter operating at 100 MS/s. Voltage and current signals are conditioned through precision attenuators and shunt resistors, then digitized simultaneously. The FPGA-based processing engine performs real-time FFT, harmonic decomposition, power calculation (active, reactive, apparent), and integration with sub-microsecond timing precision.
Key Advantages:
- Highest sampling rate in its class (100 MS/s) for capturing fast transients in SiC/GaN inverter testing
- True simultaneous sampling eliminates phase errors between channels
- CE certified for unrestricted deployment in European markets
- Direct compatibility with all WT5000 mainframe configurations
Applicable Industries:
- Electric Vehicle (EV) powertrain testing
- Renewable energy inverter validation (solar, wind)
- Industrial motor and drive efficiency certification
- Aerospace and defense power system qualification
- Railway traction power analysis
Installation Requirements:
- Mount in a WT5000 mainframe chassis (slot position configurable)
- Ensure adequate ventilation: minimum 100 mm clearance on all sides
- Connect via dedicated high-speed shielded cables (BNC type)
- Ground the chassis to earth ground with impedance < 4 Ω
Usage Precautions:
- Never exceed the maximum input voltage of 1100 V peak or current of 5.5 A peak — permanent damage will occur
- Allow 30-minute warm-up period before performing precision measurements
- Use only Yokogawa-approved shielded cables to maintain CMRR performance
- Store in environment with temperature 0°C to 40°C, humidity 20% to 80% RH (non-condensing)
