Hi, We have been using pfc corrected power supplies where each harmonic has met the requirements of EN61000-3-2 Class A limits. Investigating some new ranges of power supplies, we find that some individual harmonic currents exceed the limits. The manufacturers have quoted sections 3Z1, 3Z3, 6.2.3.3 & 7 as reasons why they pass the requirements of the standard.
Can anyone explain in plain English the meaning of these paragraphs with respect to the limits for class A and the measurements of individual harmonics? Many thanks, Neil Helsby ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
