VLT® MCC102 du/dt Filter

Click link to view brochure

du/dt filters reduce the du/dt values on the motor terminal phase-to-phase voltage – an issue that is important for short motor cables.

The du/dt filters reduce the motor insulation stress and are recommended in applications with risk of flashover.

Compared to sine-wave filters, du/dt filters cut off frequencies above the switching frequency. Having small inductance and capacitance, the price of the filter is lower.

MCC 101 Sine wave filters

Mcc101180x130

Sine-wave Filters provide a sinusoidal phase-to-phase motor voltage and reduce motor insulation stress and eliminate switching acoustic noise from the motor. Bearing currents are also reduced, especially in larger motors above 50 kW.

VLT® AHF 005 & AHF 010 Harmonic Filter

Ahf005180x130

The Danfoss AHF 005 and AHF 010 are advanced harmonic filters not to be compared with traditional harmonic trap filters. The Danfoss harmonic filters have been specially designed to match the Danfoss frequency converters.

By connecting the Danfoss harmonic filters AHF 005 or AHF 010 in front of a Danfoss frequency converter the total harmonic current distortion generated back to the mains is reduced to 5% and 10% respectively.
