Product Information
Powerful yet compact, the ACH550 delivers a 22 kW output with a rated I2n of 44 A and IP21 protection. This feature translates to precise speed control for fans and pumps, reducing energy use and thermal stress. In HVAC and process cooling applications, the drive maintains consistent torque and smoother starts, minimizing mechanical wear and emissions. Fast, straightforward commissioning is another core benefit. Preconfigured motor routines and a familiar ABB interface shorten setup time, helping panel builders meet tight project deadlines. In conveyors and material handling, the drive seamlessly integrates with existing control architectures, supporting reliable feedback and fault diagnostics. Built-in protections and safe operation provide business value. Overload, overcurrent, and short-circuit protection shield motors and wiring, while thermal monitoring prevents unexpected shutdowns. CE compliance and IP21 enclosure design give you confidence in indoor installations and regulated environments. Communication and compatibility extend the value beyond installation. Fieldbus and basic integration with ABB's control ecosystem simplify monitoring, remote tuning, and firmware updates. The drive's compatibility with standard motors and common wiring schemes reduces spare-part diversity and spares inventory. From a maintenance perspective, the ACH550's diagnostics and predictable performance contribute to lower total cost of ownership. Reduced energy consumption and longer motor life translate into faster ROI for facilities managers and OEMs in industrial automation.
