ABB 3AXD50000428984 Drive - Ultra-low Harmonics UL 50 HP
Part Number: 3AXD50000428984
Quick Summary
ABB 3AXD50000428984 Drive is a compact LV AC controller for water and wastewater pumping. Operators often wrestle with harmonic distortion, energy waste and space constraints in compact plants and municipal stations. This ultra low harmonic variant delivers THDi well under 3 percent, with an integrated low harmonic line filter and IP21 enclosure, while optional IP55 or flange mounting broadens installation options. The drive also supports intuitive commissioning and control via Hand-Off-Auto panels, Drive Composer, and an optional Bluetooth panel. By combining strong harmonic suppression with robust pump control and a small footprint, this solution translates into lower operating costs and greater system reliability for water utilities and wastewater facilities.
Product Information
Extended Description
3AXD50000428984 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.
