ABB ACS310-03U-34A1-2 LV AC Drive for Pumps & Fans - CE Certified
Part Number: 3AUA0000049478
Quick Summary
The ABB ACS310-03U-34A1-2 LV AC drive module for pumps and fans delivers precise variable torque control. Operators often struggle with energy waste and unstable throughput when using fixed-speed drives, leading to higher operating costs and wear. The solution features built-in PID controllers and pump-and-fan control (PFC), backed by CE certification and IP-rated housing for industrial environments. This combination delivers reliable performance with quick parameterization, enabling efficient pump control and fan regulation while reducing energy consumption. In addition, its compatibility with standard automation architectures supports streamlined integration and improved total cost of ownership for HVAC and process applications.
Product Information
Extended Description
3AUA0000049478 ABB: The ACS310 drives are designed for variable torque applications such as booster pumps and supply and return fans. The drive includes a powerful and beneficial set of features designed for pump and fan applications. These features include built-in PID controllers and pump and fan control (PFC) that varies the drive=E2=80=99s performance in response to changes in pressure, flow or other external data.
Feature → Business Impact → Application: Built-in PID controllers provide precise feedback-based regulation, reducing overshoot and maintaining target pressure or flow, resulting in energy savings and reduced mechanical wear in booster pumps and pressure-driven systems. This enables stable operation in fluctuating load conditions, suitable for HVAC and water-handling networks. Feature → Business Impact → Application: Pump and Fan Control (PFC) adjusts the drive’s performance in real time as external data changes, delivering responsive system behavior and improved process control, ideal for demand-based control in supply/return fan loops. Feature → Business Impact → Application: Compact, LV drive design simplifies cabinet integration and wiring, accelerating installation and minimizing panel space, which lowers commissioning time and supports scalable deployments across multiple machines. Feature → Business Impact → Application: Robust protection and reliability features common to the ACS310 family help reduce maintenance cycles and downtime, enhancing overall equipment effectiveness in demanding industrial environments. Feature → Business Impact → Application: Industry-ready certifications and standardized interfaces enable easier compliance and smoother integration with ABB and non-ABB controllers, reducing engineering effort for HVAC and pumping projects.

FAQs
Install the ACS310-03U-34A1-2 LV AC drive alongside standard motor starters, connect the three-phase supply and motor per manufacturer wiring diagrams, and configure the built-in PID and PFC parameters to match the system curve. The result is smoother start-stop behavior, reduced pump head fluctuations, and improved energy efficiency, especially in variable-torque HVAC loops.
Expect 10 Hp nominal power with a current rating around 34.1 A, designed for variable-torque control on booster pumps. The drive offers built-in PID and pump/fan control capabilities to maintain target pressure or flow, improving stability, reducing pump wear, and delivering energy savings through speed modulation instead of throttling.
Yes, the drive is suitable for supply and return fan applications where variable torque control is beneficial. Benefits include simplified integration into existing control architectures, reduced panel space due to its compact LV design, and the ability to parameterize for fan duty cycles, which lowers energy consumption and improves overall system responsiveness.
Ensure CE certification for EU safety and environmental compliance. The drive typically accommodates IP-rated environments, and ABB notes indicate SIL readiness can vary by configuration, so confirm the specific safety integrity level requirements with ABB for your installation and control system.
ROI comes from energy savings due to precise PID and PFC-enabled speed control, reduced mechanical wear from smoother torque management, and faster commissioning with familiar ABB interfaces. In HVAC and pumping applications, users often see payback within months to a couple of years, depending on system load, duty cycle, and maintenance costs.
