Interpretation of the second set of requirements applicable to Class C equipment with a
rated power ≥ 5 W and ≤ 25 W according to 7.4.3 of IEC 61000-3-2:2018 and
IEC 61000-3-2:2018/AMD1:2020.
Introduction
The second set of requirements of 7.4.3 of IEC 61000-3-2:2018 and
IEC 61000-3-2:2018/AMD1:2020 requires that “the waveform of the input current shall be such
that it reaches the 5 % current threshold before or at 60°, has its peak value before or at 65°
and does not fall below the 5 % current threshold befor
