Impulse Test Generator

Impulse Test Generator SUG-CCITT-A (Circuit 1, 10/700μS, according to Figure D.1/ Table D.1 in IEC 62368-1:2018 Annex D, Figure K.1/ Tabke K.1 in IEC 60065:2014 Annex K , and Figure N.1/ Table N.1 in IEC 60950-1:2005 Annex N).

Standard:
IEC 62368-1:2018 “Audio/video, information and communication technology equipment – Part 1: Safety requirements”
IEC 60065:2014 “Audio, video and similar electronic apparatus – Safety requirements”
IEC 60950-1:2005 “Information technology equipment – Safety – Part 1: General requirements”

Circuit reference 1 of Table D.1 generates 10/700 μs impulses (10 μs virtual front time, 700 μs virtual time to half value) as specified in ITU-T Recommendation K.44 to simulate lightning interference in the TELECOMMUNICATION NETWORK.
