ABB 3AXD50000429028 AC Drive - Ultra-Low THDi <3%
Part Number: 3AXD50000429028
Quick Summary
ABB 3AXD50000429028 AC drive delivers ultra-low harmonic control for water and wastewater pumping applications. This solution addresses energy waste and equipment wear caused by harmonic distortion in municipal pumping systems. The ultra-low harmonic variant achieves THDi below 3%, powered by an integrated low harmonic line filter that eliminates the need for external filters or complex multi-pulse wiring. It is UL-listed and CE-certified, with IP21 enclosure as standard and optional IP55 or flange-mount variants to suit diverse plant layouts. By pairing built-in pump-application features with easy commissioning tools like Drive Composer and Hand-Off-Auto control, utilities can boost energy efficiency, reliability, and operational flexibility in demanding water- and wastewater processes.
Product Information
Extended Description
3AXD50000429028 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.
Feature: Ultra-low harmonic performance is engineered to deliver THDi below 3 percent, dramatically reducing harmonic distortion in the electrical network. Business Impact: This improves power quality, helps meet low-harmonic standards, and reduces nuisance trips and EMI concerns for upstream equipment. Application: ideal for municipal water and wastewater pumping stations where uninterrupted operation and grid compliance matter. Feature: Integrated supply unit and low harmonic line filter remove the need for external filters or multi-pulse arrangements. Business Impact: simplifies installation, reduces BOM and panel footprint, lowers total cost of ownership. Application: retrofit or new builds in space-constrained plants. Feature: Output voltage boost and power factor correction enhance motor performance. Business Impact: maintains torque, improves efficiency, and reduces energy losses in variable-torque pumping. Application: energy-optimized pumping in water networks. Feature: Built-in pump-application functionality like sensorless flow calculation, multipump control, level control, soft pipe fill, dry run protection, quick ramps, and impeller cleaning. Business Impact: delivers precise process control, extends pump life, and minimizes downtime. Application: reliable operations in water transfer and wastewater handling. Feature: Usability and integration tools including Hand-Off-Auto panel, Drive Composer PC tool, and optional Bluetooth control. Business Impact: accelerates commissioning, enables remote monitoring, and eases maintenance. Application: field service, control rooms, and plantwide automation installations.
