Conducted emissions pre-compliance tests peak
detection
The following figures show the peak measurement of the conducted noise at full load and
nominal mains voltages. The limits shown on the diagrams are relevant to the EN55022
Class-B, the most popular norm for domestic equipment using a two-wire mains connection.
As shown, a good margin of the measures with respect to the limits is achieved in all test
conditions.
