Profile:

KDCW-20 is an automatic combined wave test system with PLC and computer control. It features dual waveform output, automatic polarity switching and 100MHz sampling, ensuring accurate and reliable surge protector performance testing.

Features:

  • Generates standard combination wave: 1.2±30%/50±10%μs voltage, 8±10%/20±10%μs current (no decoupling load)
  • Automatic positive/negative polarity switching, with separate setting of impulse times for each polarity
  • PLC + 10-inch touchscreen control, supporting automatic/manual trigger and parameter preset
  • 100MHz oscilloscope + dedicated software for waveform analysis, data storage and report generation
  • Built-in decoupling capacitor/inductor and 5-500V/5A action load power supply
  • Comprehensive safety interlocks: emergency stop, door limit switch, high-voltage grounding and overcurrent protection
  • Mobile cabinet with casters for easy on-site positioning and installation
