Harmonic distortion

If there are requirements for harmonics distortion level, then typically a

mains choke is needed. Total harmonic distortion is about 40...45 %, when

mains choke types CHK-xx are used according to default selection. Then

typically also the requirements for harmonic distortion according to

standards IEC 61000-3-2, IEC 610003-4 and IEC 610003-12 are fulfilled.

A more accurate harmonics analysis can be made with sizing tool DriveSize.
