Product Information
Extended Description
3AXD50000428809 ABB: The ACQ580-31 drives deliver innovative pump features for the water and wastewater industry, securing energy efficient flow of water and wastewater in your pumping solutions. The ultra-low harmonic variant provides ultimate harmonic performance, reaching even less than 3 % THDi, and exceeding the requirements set by low harmonic standards and recommendations. The drive includes an active supply unit and integrated low harmonic line filter, meaning there is no need for external filters, multi-pulse arrangements or special transformers.
Other features include output voltage boost and power factor correction. This robust and compact wall-mounted drive has built-in pump application functionality such as sensorless flow calculation, multipump control, level control, soft pipe fill, dry run protection, quick ramps and a solution for keeping the impeller of the pump clean. Usability is further enhanced with the intuitive Hand-Off-Auto control panel, the PC tool Drive composer and an optional Bluetooth=C2=AE control panel. The ultra-low harmonic wall-mounted variant comes in IP21 enclosure as standard. Also, IP55 and flange mounting units are available.
Ultra-low harmonic technology reduces input distortion through an integrated active supply unit and built-in low harmonic line filter. This lowers upfront and maintenance costs by eliminating the need for external filters, multi-pulse arrangements or dedicated transformers, while improving power quality across the plant. The business impact is clear: steadier voltage, reduced electrical stress on motors, and easier compliance with harmonic limits in critical water and wastewater networks. The application is ideal for municipal pumping stations and industrial process pumps requiring dependable power quality without complex external infrastructure. Output voltage boost and power factor correction enhance motor performance under variable loads, delivering measurable efficiency improvements and better site-wide energy metrics. This is especially valuable for variable-torque pumps where peak demand can spike at odd hours. Sensorless flow calculation, multipump control, level control, soft pipe fill, and dry run protection are built-in, reducing equipment wear, preventing dry running, and delivering smoother process control. Quick ramps and impeller cleaning support reliable operation during startup cycles and extended run times, translating to lower maintenance costs and longer pump life. Hand-Off-Auto control panel together with Drive Composer PC tool simplifies commissioning and operator training, while an optional Bluetooth control panel provides field-accessible monitoring. The drive’s compatibility with the ABB ecosystem reduces integration risk in retrofits and new builds. IP21 is standard, with IP55 and flange mounting options available to match site requirements, and the integrated low harmonic drive eliminates the need for external filters and transformers—streamlining installation in compact spaces.
