Part Number: 3AXD50000428779
Quick Summary
ABB 3AXD50000428779 is a LV AC wall-mounted ultra-low harmonic drive designed for water and wastewater pumping. It reduces harmonic distortion and energy waste while simplifying installation in tight spaces. The unit ships with UL and CE certifications and standard IP21 protection, with IP55 and flange mounting options available for harsher environments. Built-in features such as a low harmonic line filter, an active supply unit, and pump-specific controls accelerate commissioning and improve reliability. User-friendly interfaces like Hand-Off-Auto, Drive Composer, and an optional Bluetooth panel support remote monitoring, maintenance, and faster response to plant dynamics, delivering measurable reductions in operating costs and lifecycle risk.
Product Information
Extended Description
3AXD50000428779 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.
