IWT-1000L surge tester

IWT-1000L is an Impulse Winding / Surge Tester specially designed for ultra low inductance coil testing, offering programmable DC test voltage from 10V to 1000V with extremely high sampling rate at 200MHz. The inductance range to be tested is from O.luH up to SOmH, which covers nearly all that of various coil DUTs including high-power inductance, transformer, wireless charger coils … etc. The main purpose of IWT-1000 L is to find pre-exisiting defects, caused by poor winding, insulation, magnet parts, of components by comparing the waveform with that of the Master sample, and to ensure you of long-term reliable end products.
  • Ultra Low Test Inductance Range – O.luH.
  • 10V~1000V Programmable DC Voltage with minimum out-put energy that causes n odamages to DUTs.
  • High Sampling Rate at 200MHz for better detection of discharges.
  • Four Wavefrom Comparison methods AreaSize, DiffZone, Corona Amount, Corona Number Comparison for simple & fast testing.
  • Extremely Low Test Voltage Steps for best wavefrom analysis.
  • Two Coaxial 4-Wire Cables for most precise waveforms oflow inductance DUTs.
  • Intuitive result display of Pass/Fail icons.
  • Internal memory storage of 360 waveforms.
  • User-friendly operation interface.
  • Inductance differential voltage compensation function.
  • PC/PLC communication via standard RS-232 string command for building automated testing system.
  • PC connection via USB 2.0 & RS-232, capable of uploading waveforms and data to PC in Excel format for easy analysis and records.
  • External I/O(Handler) control via standard 15Pin D-Sub connector for automated system integration and direct foot switch of starting tests.
