Conducted emission pre-compliance test

The following figures are the peak measurements of the conducted noise emissions at full

load and nominal mains voltages. The limits shown on the diagrams are those of EN55022

Class-B, which are most popular requirements for domestic equipment and imposes less

stringent limits compared to the Class-A, which is dedicated to IT technology equipment. As

visible in the diagrams, in all test conditions there is a good margin for the measurements

with respect to the limits.
