The intelligent choice for harmonic mitigation

Enjoy harmonic mitigation, power factor correction, and imbalance compensation, all in one product. You can adjust the settings to your needs and put focus on the area that is important in your application.

Selective harmonic mitigation and automatic resonance detection ensure reliable operation tailored to your application requirements.

> 98.2% filter efficiency using advanced SiC technology

The Danfoss Advanced Active Filter AAF 007 is designed to reduce harmonic distortion of central or decentrally installed Danfoss drives. The newest-generation SiC switches give unmatched high efficiency with 60% lower power losses compared to similar filters and effective elimination of high-order harmonics. The filter is compatible with all drives in the Danfoss product portfolio, and is delivered pre-configured and tuned from factory, ready to use with the accompanying current transducers.

Line voltage and filter current*

  • 3 x 380-480 V AC ... 55 A modules. Maximum 440 A with 8 modules mounted in parallel

*Additional voltage ranges and filter currents are available on request.

Features and benefits

    Variable speed control of a chiller allows you to provide constant pressure regulation while matching the capacity to the actual need based on measurements in the system. Speed control is beneficial when a compressor runs for long periods at partial load. Reduce operational costs by running applications at a lower speed which reduces energy consumption. And reduce installation costs by optimizing the system and the compressor itself.
