Conducted noise measurements

A pre-compliance test for the EN55022 (Class B) European normative was also performed

on both average and peak measurements of the conducted noise emissions at full load and

nominal mains voltages.

Figure 30 to 33 show the results. As seen in the diagrams, in all

test conditions there is a good margin for the measurements with respect to the limits, also

using the peak detector.
