Profile:

The KDZG-II is a portable DC high-voltage generator designed for high-voltage testing, built to meet ZGF24003-90 standards. It uses a medium-frequency voltage doubling circuit with PWM modulation and IGBT technology, delivering stable 0–400kV DC output with low ripple (≤0.5%). Housed in a compact epoxy glass insulation cylinder, it features a control box with digital displays, a built-in 0.75UDC-1mA button for ZnO arrester testing, and multiple safety protections. With imported components and a lightweight design, it is ideal for field and lab testing of power equipment.

Features:

  • Compact, lightweight design for easy field deployment and outdoor use.
  • PWM medium-frequency modulation and voltage feedback ensure stable high-voltage output with low ripple.
  • High-precision 0.75UDC-1mA one-touch button for simplified ZnO arrester testing.
  • Digital displays for voltage (0.1kV resolution) and current (0.1μA resolution) for accurate readings.
  • Multiple safety protections: over-voltage, over-current, zero-start, ground, and disconnection protection.
  • Built-in 75% voltage function key for direct leakage current testing without manual calculation.
  • Imported IGBT components and US-made voltage multiplier cylinder for reliability and overload capacity.
  • Vertical/horizontal compatible control box design for stable setup on-site.
  • USB/serial communication options for data integration and remote control.
