EMS61000-4A Intelligent Electrical Fast Transient Generator
EMS61000-4A Intelligent Electrical Fast Transient Generator is suitable for electrical fast transient impulse group immunity test occasions. It simulates the interference caused by many mechanical switches (switching inductive loads, relay contact bouncing, etc.) in power grid. It has good transient pulse waveform, high pulse repetition rate (up to 2MHz), stable performance, easy operation, fully conforms to the latest IEC (International Electrotechnical Commission) standard IEC 61000-4-4, European electrical standard EN61000-4-4, and national standard GB/T17626.4. It is an ideal interference source for EMC test.
