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.
