Profile:

KDZG-II 400kV/2mA is a split-type DC high-voltage generator adopting PWM technology and IGBT devices. It features stable output, low ripple and multiple protections, with compact control box and foldable feet for reliable on-site operation.

Features:

PWM pulse width modulation technology ensures high voltage stability (≤1%) and low ripple coefficient (≤1%)
One-key 0.75UDC1mA function for precise zinc oxide arrester testing (accuracy ≤1.0%)
Digital display with ±(1.0% reading±2 digits) accuracy for voltage and current measurement
Dial switch for intuitive overvoltage protection setting, error ±1%
Epoxy FRP voltage doubling cylinder with air insulation, no leakage risk
Foldable "Y" type feet and small control box for enhanced stability and portability
Zero-start voltage regulation with smooth adjustment (accuracy ≤0.5%) and comprehensive protections
