Profile:

KDVLF-TD is an integrated ULF tester with multi-waveform output (sine/DC/rectangular wave). It features automatic testing, USB data export and multi-language UI, enabling accurate and efficient cable insulation assessment.

Features:

  • Integrates ULF withstand voltage, dielectric loss, DC leakage and sheath tests in one unit
  • Multi-waveform output: 0.1Hz sine wave, DC voltage and rectangular wave for diverse test needs
  • Automatic frequency adjustment (0.01Hz-0.1Hz) adapting to cable capacitance
  • Real-time display of waveform, tanδ, capacitance and resistance with 1% measurement accuracy
  • Automatically tests at 0.5U0, U0, 1.5U0 and generates insulation health assessment reports
  • USB 2.0 interface for data export and firmware update, supports multi-language operation
  • Compact Peli Case packaging (22kg) for easy transportation and on-site use
