Profile:

KDZG-II is a portable DC withstand voltage test bench adopting PWM intermediate frequency technology and IGBT devices. It features stable voltage output, multiple protections and compact design, ideal for on-site and laboratory high-voltage insulation testing.

Features:

  • PWM intermediate frequency pulse width modulation technology for high voltage stability and low ripple coefficient
  • Built-in 0.75UDC-1mA function for convenient zinc oxide arrester testing with one-key operation
  • Digital display of voltage (resolution 0.1kV) and current (resolution 1μA) with high measurement accuracy
  • Multiple protection functions: overvoltage, overcurrent, zero-start, grounding and wire breakage protection
  • Epoxy glass fiber reinforced plastic voltage doubling cylinder with air insulation, no leakage risk
  • Vertical/horizontal dual-purpose chassis and built-in support feet for enhanced stability during on-site use
