Conducted emission pre-compliance test

Figure 18 and 19 show the average measurement of the conducted noise at full load and

nominal mains voltages. The limits shown on the diagrams are EN55022 Class-Bs, which is

the most popular rule for domestic equipment and has more severe limits compared to

Class-A, dedicated to IT technology equipment. As shown in the diagrams, in all test

conditions the measurements are far below the limits.
