Important user notice
Schaffner sine wave filters are designed for the operation on the output (motor) side of converters,
such as AC or DC motor drives. Filter suitability for a given application must be determined by the user
on a case by case basis. Schaffner will not assume liability for any consequential downtimes or dam-
ages resulting from use or application of Schaffner sine wave filters beyond their specifications.
Schaffner sine wave filters are not designed for single-phase or split-phase applications.
