Profile:

Built with advanced mid-frequency PWM pulse-width modulation and closed-loop voltage feedback, the KDZG-II ensures exceptional output stability (≤1%) and low ripple (≤2%). Featuring premium IGBTs and imported components from the U.S., Germany, and Japan, its epoxy-glass fiber multiplier tube offers high overload capacity and resilience—even under direct short-circuit discharge. The cabinet-style design balances portability (total weight: 11 kg) with robust performance for demanding field environments.

Features:

  • Output: 0–60 kV (negative polarity), 10 mA rated; 600 W max power
  • One-Touch 0.75UDC@1mA Function: Simplifies ZnO arrester testing—press button at 1 mA to instantly read 75% reference voltage (accuracy ≤1%)
  • Dual Leakage Current Measurement: High-voltage end (circular shielded digital display) and low-voltage end for accurate, interference-free readings
  • High Resolution: Voltage ±0.1 kV, current ±1 µA; no external divider required
  • Smooth Voltage Control: Full-range adjustment via precision multi-turn potentiometer
  • Comprehensive Protection: Overvoltage (digital dial-set), overcurrent, zero-start interlock, grounding, open-circuit detection, and automatic shutdown
  • Capacitive Load Ready: Unlimited specimen capacitance; supports 1.25× rated charging current (12.5 mA)
  • Field-Optimized Design:
    • Air-insulated, oil-free epoxy-glass multiplier tube (700 mm height)
    • Total system weight: only 11 kg (control box: 4.5 kg; multiplier: 6.5 kg)
    • Operates up to 10 minutes continuously per cycle
  • User-Friendly Interface: Digital overvoltage setting (in kV), intuitive controls, and rugged cabinet form factor
