Danfoss Introduces A New Advanced Harmonic Filter for Optimized Drive Performance
LOVES PARK, IL -- Danfoss North America Motion Controls (NAMC) introduces the Advanced Harmonic Filter (AHF). These filters offer cost-effective harmonic reduction despite ever-present background disturbances, such as phase unbalance and background voltage distortion, to provide optimized 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. 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 specialized start-up. One filter module can be used in conjunction with several variable frequency drives.

Danfoss is a leading manufacturer of precision mechanical and electrical components, with locations in more than 120 countries. Danfoss created the VLT name when they introduced the world’s first mass-produced AFD in 1968, and the name has set the standard for high performance quality variable frequency drives ever since.
