The filters are current-rated devices. In order to properly size a filter, it is necessary to know the operating

voltage and the input current rating of the drive. No derating or re-rating is necessary when applying the filter at

voltages that are less than or equal to the maximum voltage listed on the filter.

The IEEE 519-1991 Standard

The Institute of Electrical and Electronics Engineers (IEEE) has developed a standard that defines acceptable

limits of system current and voltage distortion. A simple form is available from McQuay that allows McQuay to

determine compliance with IEEE 519-1991.

Line reactors, isolation transformers, or phase-shifting transformers can be required on some installations.
