Dear Group, Here are a couple of questions from our EMC department.
1) EN61000-3-2 Clause 7.4. states that "The limits given in table 3 are valid for all applications having an active input power >75W. No limits apply for equipment with an active input power up to and including 75W. This lower limit of 75W will be reduced to 50W, four years after the implementation date of this standard." Does anyone know when this 4 year period starts? (from 1995 when the standard was issued, or from January 1, 2001 when the standard becomes mandatory? 2) Can someone make clear the discontinuous interference limits for EN55022,EN55011? Generic standards (EN50081-1 and EN50081-2) has limits for discontinuous interference referencing EN55014, but EN55022 nor En55011 do not. Another complication arises when there is a specific product standard, in which case we shouldn't use a generic one. Any help on the above will be appreciated. Sincerely, Frank F.
