ABB 3AXD50000428304 LV AC Drive - Ultra-Low THDi <3%
Part Number: 3AXD50000428304
Quick Summary
The ABB 3AXD50000428304 LV AC Drive delivers ultra-low harmonic control for water and wastewater pumping applications. Engineers wrestle with harmonic distortion, energy waste, and the burden of external filters and transformers. CE marking and IP-rated enclosures—IP00 standard with IP20 options—support safer, compliant field installations. The drive integrates an active supply unit and an integrated low harmonic line filter, eliminating the need for external filters or multi-pulse transformers. Output boost and power factor correction improve motor efficiency, while built-in pump application features such as sensorless flow calculation, multipump control, and level management enhance process accuracy. In short, it lowers operating costs, reduces BOM complexity, and accelerates commissioning in municipal and industrial pump systems.
Product Information
Extended Description
3AXD50000428304 ABB: The ACQ580-34 drives deliver innovative pump and blower 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 drive module 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 drive module variant comes in IP00 enclosure as standard and is installed into a cabinet. Also, IP20 enclosure is available.
Ultra-low harmonic performance delivers THDi under 3% through an integrated low harmonic approach. This translates to lower harmonic distortion in pump systems, reducing energy waste and the need for external filters or multi-pulse transformers. It is particularly beneficial for water and wastewater pumping stations where grid compliance and power quality impact reliability and maintenance costs. Built-in active supply unit and integrated low harmonic line filter simplify cabinet design. By eliminating external filters and transformers, installation time drops and BOM complexity decreases, saving both space and cost. This configuration is ideal for compact cabinets in municipal facilities, where space and serviceability matter most. Output voltage boost and power factor correction improve motor efficiency and reduce reactive power demand. The payoff is lower energy consumption, cooler operation, and extended motor life, especially for aging pumping fleets. Applications include pump and blower modules where energy performance is critical for operating budgets. Integrated pump-specific functions—sensorless flow calculation, multipump control, level control, soft pipe fill, dry-run protection, and quick ramps—advance process control. These features support precise dosing, smooth start/stop sequences, and reliable operation under fluctuating demand. They also reduce instrumentation costs by delivering advanced control within the drive. User-friendly interfaces—Hand-Off-Auto control panel, Drive Composer PC tool, and optional Bluetooth panel—shorten commissioning and simplify maintenance. IP00 standard enclosure is compact for cabinet installations, while IP20 options expand installation flexibility in harsher environments. The result is faster deployment, easier diagnostics, and fewer on-site visits. Compatibility with ABB motor drive ecosystems and built-in protections ensures resilience in demanding water and wastewater environments. The ultra-low harmonic module integrates with standard 400 V distribution and supports consistent pump performance even under variable loads. This translates to predictable ROI through reduced downtime and optimized energy use.

FAQs
For cabinet installations, ensure the drive is mounted in an appropriately rated enclosure (IP00 standard, IP20 option available) and that the internal space accommodates the integrated active supply unit and low harmonic filter. Use the standard 400 V distribution variant and plan for sensorless flow and multipump wiring. The integrated filters reduce the need for external equipment, simplifying wiring and increasing cabinet reliability during service.
THDi under 3% minimizes harmonic distortion, aiding compliance with grid codes and reducing transformer and switchgear loading. This translates to lower energy losses, improved power factor, and reduced cooling requirements in pumping stations. The result is lower operating costs and smoother operation of pumps and blowers in water and wastewater facilities.
Yes. The drive includes built-in pump application features such as multipump control and sensorless flow calculation, enabling coordinated operation of multiple pumps and optimized sequencing. This reduces wear, improves process control, and lowers energy use for variable demand typical in wastewater treatment and flood-control pump stations.
The unit supports CE marking for European compliance and offers IP00 enclosure as standard, with IP20 enclosure options for harsher environments or tighter cabinets. While the data does not specify SIL, the device provides robust protective features and safety interfaces suitable for municipal and industrial pump systems, aligning with typical regulatory expectations in these sectors.
ROI improves through energy savings from improved motor efficiency and lower reactive power, plus reduced BOM and wiring complexity due to the integrated low harmonic filter. Maintenance benefits include fewer external components, simpler commissioning with Drive Composer, and fewer on-site visits thanks to easier diagnostics and built-in protections that extend motor life and reduce downtime.
