Profile:

KDZG-II is a portable DC high-voltage generator adopting PWM technology and IGBT devices. It features high voltage stability, low ripple and multiple protections, with compact design and easy operation for reliable on-site testing.

Features:

  • PWM intermediate frequency modulation technology ensures high voltage stability (≤1%) and low ripple (≤0.5%)
  • High-precision digital display with 0.1kV voltage and 1μA current resolution
  • One-key 0.75UDC-1mA function for convenient zinc oxide arrester testing (accuracy ≤1.0%)
  • Multiple protections: overvoltage, overcurrent, zero-start, grounding and wire breakage protection
  • Digital dial switch for intuitive overvoltage setting, no external voltage divider needed
  • Epoxy glass fiber reinforced plastic voltage doubling cylinder with air insulation, no leakage
  • Built-in support feet and convertible control box base for enhanced stability
