The ABB ACQ580-01-206A-4 is a high-power, 206 Ampere, 110 kW (150 HP) variable frequency drive from the ACQ580 series, specifically engineered for Quadrant Operation and Regenerative Applications. Unlike standard drives, the ACQ580 utilizes Active Front End (AFE) technology, enabling it to actively control power flow in both directions—drawing power from the grid to motor the load and feeding regenerated energy cleanly back to the grid with ultra-low harmonic distortion.
