The ultra-low harmonic drives achieve a unity power factor. This high power factor indicates that the electrical energy is used to its full potential.
The drive offers a possibility for network power factor correction in order to compensate for low power factors of equipment connected to the drive. It reduces the need for additional power factor correction equipment, such as filters and large capacitor banks. It can also help to avoid penalty charges set by electrical utilities for poor power factors.
As harmonic currents are reduced, equipment wastes less energy and energy efficiency is considerably improved.
