EFT and Surge Generator is applied to check the performance of the power cable and inner electrical circuit of equipment (home appliances, communication electronics, electrical components, auto control system and etc.) against the high energy transient interference caused by switching and lightning transients. The equipment meet the requirements of IEC61000-4-5 and IEC61000-4-4.
Burst and surge generator is a 2 in 1 equipment, it can do both the fast transient immunity test and surge immunity test in an economic way.
