ACQ580-01-073A-4

The ABB ACQ580-01-073A-4 is a 73 Ampere, 37 kW (50 HP) variable frequency drive from the ACQ580 series, which is specifically engineered for Quadrant Operation and Regenerative Applications. Unlike standard drives that only consume energy, the ACQ580 is designed as an Active Front End (AFE) drive, meaning it can 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.

Key Specifications Parameter Category Specification Drive Series/Model ACQ580-01-073A-4 Rated Output Current 73 A Rated Output Power 37 kW (50 HP) Input Supply Voltage 380 - 480 V AC (± 10%), 3-phase Input Supply Phases 3-phase Output Voltage/Phases 3-phase, 0 - Input voltage Enclosure Rating IP21 / UL Type 1 (Standard for -01) Cooling Method Fan-cooled Topology Active Front End (AFE) / Regenerative Drive with IGBTs on both the input and output sides. Control Method ABB Direct Torque Control (DTC) Key Standard Features • Four-Quadrant Operation: Full motoring and regenerative braking capability. • Ultra-Low Harmonics: Input current THDi < 5% (meets IEEE 519-2014 without external filters). • Unity Power Factor: ~1.0 across the entire speed and load range. • Regeneration to Mains: Feeds braking energy back to the supply network, improving energy efficiency. • Intelligent Control Panel (IOP) with graphical display. • Common DC Bus Capable for multi-drive systems. Protection Features • Comprehensive motor and drive protection. • Mains phase loss and undervoltage protection. • Grid feedback protection (for reverse power conditions). Application Focus Applications with frequent braking or overhauling loads: Centrifuges, Cranes & Hoists, Downhill Conveyors, Test Benches, Wire Drawing Machines. Also for installations with strict harmonic limits.
