Product Information
Extended Description
3AXD50000046646 ABB: ACH580 HVAC drive offering has all key features built-in to control fans, pumps and compressors, and more complex equipment like air-handling units and chillers, ensuring smooth, energy-efficient operation of your HVAC systems in normal and mission-critical situations. This ultra-low variant provides ultimate harmonic performance, reaching even less than 3 % THDi, and exceeding the requirements set by low harmonic 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. The built-in features significantly reduce installation time, and the intuitive HVAC specific control panel and help assistants make operation easy. The optional Bluetooth=C2=AE capability enables the commissioning and monitoring of the drive from a distance. The variant comes in IP21 enclosure as standard and can be installed on the wall. Also, IP55 and flange mounting units are available.
Integrated active supply unit and an integrated low harmonic line filter eliminate the need for external filters and complex multi-pulse arrangements, reducing installation time and material costs while delivering a cleaner electrical environment for HVAC equipment. This directly improves equipment reliability and longevity, enabling fans, pumps, and compressors to run with steadier torque and less electrical noise. The THDi performance of the ultra-low harmonic variant helps meet stringent power quality standards, reducing nuisance trips and potential penalties in regulated facilities and data centers. The IP21 enclosure and wall-mount design offer flexible installation in mechanical rooms and control panels, with IP55 and flange-mount options for harsher environments, minimizing space constraints and simplifying retrofits. Built-in HVAC-specific control features and a intuitive UI accelerate commissioning, decreasing on-site labor and startup risk. Optional Bluetooth enables remote commissioning and monitoring, lowering site visits and improving maintenance planning. These capabilities collectively translate into lower lifecycle costs, faster project delivery, and stronger alignment with energy-management and automation strategies across building portfolios.
