Description

LCG C series are comprehensive impulse current testing systems with high system integration, intelligent control, easy operation. Equipped with different modules, different waveforms can be generated, ideal for one-stop testing solutions. The automatic control system allows for easy test setting, waveform switching and one-button automatic running.

Features:

  • Open structure, 3D centripetal layout, with small inductance and even discharge;
  • Easy & flexible operation with highly integrated automation (test scheduling); automatic control system: MCS 2000;
  • High capacity: impulse current up to 30 kA for Level 1, up to 200 kA for Level 2; charging voltage up to 80 kV;
  • Two waveforms, free switching;
  • Optional LCM 25D module, to raise the output current (10 / 350 μs);
