Product Information
Extended Description
3AXD50000751945 ABB: The ACH531 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 a smooth, energy-efficient operation of your HVAC systems in normal and mission-critical situations. The built-in features significantly reduce installation time and the standard basic control panel can make startup, commissioning, and operation easy. The optional Bluetooth=C2=AE capability enables the commissioning and monitoring of the drive from a distance. The ACH531-01 comes in an IP20 enclosure and can be installed on the wall as standard.
Integrated HVAC-focused control for fans, pumps, and compressors reduces system complexity and accelerates commissioning. By aligning speed profiles with load requirements, energy use drops and motor wear is minimized. In typical air handling units and cooling loops, this translates to measurable efficiency gains and improved process stability. IP20 enclosure and wall-mounting support simplify installation and reduce enclosure costs, allowing quick deployment in standard mechanical rooms and retrofit projects. Built-in basic control panel speeds startup and minimizes the need for external controllers, cutting wiring time and lowering total project cost. Optional Bluetooth enables remote commissioning and monitoring, reducing on-site service time and enabling proactive energy management across multiple sites. The 4 kW, 9.4 A rating ensures motor compatibility with common HVAC equipment while maintaining compact, space-efficient installations. This combination supports reliable operation in challenging environments and enhances overall system resilience.
