Product Information
Extended Description
3AXD50000428939 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.
Integrated low harmonic line filter and ultra-low harmonic topology deliver superior power quality, eliminating the need for external filters, multi-pulse converters, or special transformers. This reduces total installed cost and maintenance while extending motor life in demanding water and wastewater pumping environments. Sensorless flow calculation and multipump control enable precise pump sequencing, level regulation, and reduced cycling, cutting energy use and wear. Output voltage boost and power factor correction improve starting torque and efficiency under varying head conditions, while Drive Composer and Hand-Off-Auto control streamline commissioning and diagnostics. The wall-mounted design saves panel space and time during installation, with IP21 standard and IP55 optional enclosures ensuring durability in harsh plant environments. Optional Bluetooth control panel simplifies remote monitoring.
