The ABB ACS355-01U-04A7-2 is a compact machinery drive designed for precise motor control in industrial automation applications. This single-phase input drive operates on 200-240 VAC supply voltage and delivers 1.1 kW (1.5 hp) continuous output power with a rated current of 4.7 A. It features sensorless vector control for both induction and permanent magnet motors, built-in brake chopper, and Safe Torque Off (SIL3) function as standard. The drive is optimized for OEM machine builders, system integrators, and panel builders requiring rapid commissioning with application macros. Its IP20 protection rating makes it suitable for cabinet installations in material handling, food and beverage processing, textile machinery, and general industrial equipment. The ACS355 series offers exceptional compactness with uniform dimensions across the product family, enabling flexible side-by-side installation in space-constrained control panels.
