M5 Series (5% THID) The M5 Series Filters typically achieve 5% THID at full load and guarantee worst case current distortion at any load between 0% and 100%, will be 8% THID or less at the filter input terminals. The M5 Series is typically used in applications requiring harmonic mitigation associated with 18-pulse rectifiers. The chart on the right compares the performance of Filters (M5 Series) to 18-pulse rectifiers in real world applications which include line voltage unbalance of 1% to 3% and loading conditions from 0% to 100%.

M8 Series (8% THID) The M8 Series Filters typically achieve 8% THID at full load and guarantee worst case current distortion at any load between 0% and 100% will be 12% THID or less at the filter input terminals. The M8 Series is typically used in applications requiring harmonic mitigation associated with 12-pulse drives. The chart on the right compares the performance of Filters to 12-pulse rectifiers in real world applications which include line voltage unbalance of 1% to 3% and loading conditions from 0% to 100%.

Selecting Low Pass Harmonic Filters
Select Harmonic Filters based on total maximum load (rms amperes) to be connected to the filter. Harmonic filters can supply one or more loads up to their maximum load amps ratings.

Enclosure Options
Low Pass Harmonic Filters are available in a variety of enclosure options. The standard enclosure meets the requirements of both Nema 1 & Nema 2, while another option meets Nema 3R. For maximum flexibility, Harmonic filters are also offered as open panel construction for integration into customer panels and enclosures.

Suitable for any 6-pulse rectifier
Harmonic filters are compatible with either diode or SCR type rectifiers and can be used with or without internal impedance such as line reactors or dc bus chokes.
