ACS 2000, low harmonic drives
ABB’s low harmonic drives offer optimal low harmonic performance which does not require any additional filtering. Line side harmonics of the ACS 2000 are compliant with all relevant standards. This avoids the need for harmonic analysis or the installation of a multi-pulse transformer, network filters or other additional equipment for harmonics reduction.

ACS 2000, regenerative drives
ACS 2000 regenerative drives provide enhanced active braking and power factor correction.

The AFE enables regenerative braking which allows full power flow both in motoring and generating mode. Regeneration offers significant energy savings compared to other braking methods as energy is fed back to the supply network. Regeneration is especially suitable for applications with frequent starts and stops. It allows energy efficient continuous braking of applications such as downhill conveyors or expanders in gas pipelines.

The AFE can also provide reactive power (VAR) compensation. With VAR compensation, the voltage level can be controlled to stay within tight limits. A smooth network voltage profile can be maintained and reactive power penalties can be avoided.
