Conducted emission pre-compliance test
Figure 51 and 52 show the peak measurement of the conducted noise at full load and
nominal mains voltages. The limits shown in the diagrams are EN55022 Class-B, which is
the most popular rule for domestic equipment and has more severe limits compared to
Class-A, dedicated to IT technology equipment. As seen, peak measurements are below
the limits relevant to average measurement (red) and more than 10 dB below quasi-peak
limits (green).
