Product Information
Extended Description
3AXD50000940820 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.
Built-in HVAC control capabilities directly manage fans, pumps, and compressors, reducing external wiring and configuration time. The business impact is faster deployment, fewer points of failure, and improved system reliability. This is ideal for air handling units and chillers where precise motor control translates to consistent climate performance. The IP20-rated enclosure and wall-mount design simplify installation, save valuable plant space, and improve operator safety in indoor environments. Remote commissioning is enabled by optional Bluetooth, cutting site visits and accelerating startup while enabling real-time monitoring of key performance indicators. The 1.1 kW, 3.3 A drive delivers efficient speed control for HVAC loads, helping you lower energy use and heat generation during peak demand. A built-in basic control panel reduces wiring complexity and speeds up startup, especially in retrofit projects. Compatibility with ABB’s control ecosystem supports scalable automation and easier maintenance planning, further reducing lifecycle costs and downtime.

FAQs
When installing the ACH531, mount it on a stable indoor wall within reach of power and motor connections. Ensure adequate ventilation and clearance for heat dissipation, and follow the IP20 protection guidelines to protect against dust. Plan wiring routes to minimize length and interference, and use the built-in control panel where possible to simplify startup and testing.
The ACH531 provides precise speed control for fans, pumps, and compressors, reducing throttling losses and allowing systems to run closer to design duty cycles. Built-in control features enable optimized acceleration, deceleration, and fault handling, which lowers energy use during varying load conditions and improves overall system efficiency and comfort in commercial HVAC installations.
Yes, the ACH531 is designed to integrate with ABB’s broader automation portfolio. It supports standard motor drive interfaces and can be coordinated with ABB controllers and SCADA/automation layers for centralized monitoring, diagnostics, and firmware management. This compatibility simplifies retrofit projects and enables scalable control across multiple HVAC assets.
The ACH531 is built with an IP20 enclosure suitable for indoor mounting, providing basic environmental protection for typical HVAC rooms. It supports Bluetooth for remote commissioning and monitoring, enabling safer, hands-off setup. While IP20 and Bluetooth are key ratings, confirm project-specific compliance requirements with your local standards team during procurement.
The ACH531 reduces commissioning time with built-in startup features and enables remote diagnostics via Bluetooth, lowering on-site service visits. Energy savings arise from optimized HVAC motor control and reduced peak demand. Over time, maintenance costs decline due to simplified monitoring, fewer external components, and better fault visibility, delivering a favorable total cost of ownership for HVAC projects.
