Impulse current test system LCG A series is mainly used to simulate high current generated by lightening to check the impact on power supply system and electric appliance. It can conduct impulse current tests with high integration, intelligent control
and easy operation. There are multiple grades for output by different main circuit unit. With setting parameters on setting page,
it can conduct the test automatically with one button.
> Human computer interface of colorful touch screen, easy to operate;
> PLC control system, stable and reliable operation;
> Different control modes: manual, automatic or programmable, as per different needs;
> Multiple grades of output ranges, test current down to 1kA;
> Charging mode of continuous current, effectively save energy;
> Abnormal protection by audible and visual alarm;
> Automatic measure and analyze parameters of different waveforms.
