The high-voltage high-power CDN for EFT/Burst immunity tests is designed according to test requirements of IEC/EN 61000-4-4, features stable performance and convenient operation. The device is used together with CCS series and EFT series of 3ctest. Maximum EUT load capacity is AC 450 V 50 A/ DC 110 V 50 A and can also be customized according to actual EUT load.
Features：
> High capacity of EUT load;
> Automatic switching as scheduled;
> Over-current protection;
> Test sequencing for test voltage, polarity, phase sync angle etc.;
> Superposition of phase angle on random lines;
