Fact Sheet
VLT® Advanced Harmonic Filter
AHF 005 and AHF 010
Optimised harmonic performance
for VLT® drives rated up to 250 kW.
The VLT® Advanced Harmonic Filter
has been specially designed to match
the Danfoss drives for unmatched performance and design.
Compared to traditional harmonic trap
filters, the VLT® Advanced Harmonic Filter offers a smaller foot print and higher
harmonic reduction.
The filter is available in two variants,
AHF 005 and AHF 010. When connected at the input to a Danfoss VLT®
drive the harmonic current distortion
generated back to the mains is reduced
to 5% or 10% Total Harmonic Current
Distortion (THiD) at full load.
With efficiency exceeding 98 % the passive filters AHF 005 and AHF 010 offer
cost-effective and very robust harmonic
solutions specifically for power ranges
up to 250 kW.
As stand-alone options the advanced
harmonic filters feature a compact
housing that is easily integrated into
existing panel space. This makes them
well-suited for retrofit applications with
limited adjustments of the drive.

Harmonic
Calculation Software
With VLT® Motion Control Tool
MCT 31, you can determine whether
harmonics will have a detrimental
effect on an installation incorporating
frequency converters.
MCT 31 calculates system harmonic
distortion. Then it estimates the
benefits of implementing harmonic
mitigation, using filters available from
Danfoss. Furthermore the software
provides quick indication of whether
the installation complies with the most
recognised harmonic norms and
recommendations.
