Conducted emission pre-compliance test
Figure 23 and 24 show the peak measurement of the conducted noise at full load and
nominal mains voltages. The limits shown on the diagrams are the EN55022 Class-B ones,
which is the most popular rule (or standard) for domestic equipment and it has more severe
limits compared to the Class-A, dedicated to IT equipment. As shown in the diagrams, under
all test conditions the measures are within the limits.
