Harmonic filters optimise drive
performance
The AHF advanced harmonic filter offers cost-effective harmonic reduction despite ever-present background disturbances.
The AHF advanced harmonic filter offers cost-effective harmonic reduction despite ever-present background disturbances, such as phase unbalance and background voltage distortion, to provide optimised drive performance The AHF Series 005 reduces total harmonic current distortion (THiD) to less than 5%, thus providing performance similar to that of an 18-pulse drive

Drives provide engineered panel solutions
A new range of engineered panel solutions is available across the complete Danfoss family of drive products and power sizes.
These highly efficient filters suppress THvD to lower levels than is otherwise achievable with 18-pulse drives, which simply transfer the harmonics to a higher frequency.
The AHF Series 010 provides superior performance when compared with a 12-pulse drive, while reducing THiD to less than 10%.
Advanced harmonic filters feature a compact housing that is easily integrated into existing panel space, making them well suited for retrofit applications.
They are designed for simple setup with "cable-in/cable-out" installation, and require no balancing, routine maintenance, or specialised startup.
One filter module can be used in conjunction with several variable frequency drives.
