Description

LCG D series impulse current test system is a multi-pulse test generator self development by 3ctest with high integration, automation control system and easy operation. With different optional modules, it can simulate corresponding waveforms with an all-in-one high voltage test system. By setting parameters on setup page, LCG D series test system can switch all kinds of waveforms automatically only with one button.

  • Color touch screen, easy to operate
  • PLC control system, high interference immunity, stable, and reliable;
  • Two-path pulse output, delay time 0～99.9μs adjustable
  • Min. test current is about 1kA
  • Controlled silicon charging mode to save energy
  • Protection function with Audible and visual alarm
  • Measurement and analyze waveform parameters automatically
  • with MCS2000 automatic control system
