ABB ACS310-03U-25A4 LV Drive for Pumps & Fans - 25.4 A
Part Number: 3AUA0000049491
Quick Summary
ABB ACS310 LV drive module delivers variable-speed control for pumps and fans in HVAC and pumping systems. Many installations struggle with energy waste and throttled performance when pumps and fans run at fixed speeds or through poorly tuned controls. The drive includes built-in PID controllers and pump and fan control (PFC) that respond to changes in pressure, flow, or external data, delivering tighter process control and measurable energy savings. This solution aligns with typical industrial automation practices, enabling seamless integration with existing PLCs and HMI interfaces. By choosing the ACS310, you gain improved efficiency, smoother starts, and scalable performance that supports ongoing commissioning and maintenance without disrupting operations.
Product Information
Extended Description
3AUA0000049491 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.
Built-in PID controllers provide closed-loop tuning, delivering precise speed and torque regulation. This reduces overshoot and stabilizes flow, translating into consistent pump performance and less mechanical wear. Ideal for booster pumps and supply/return fans in HVAC systems, where steady operation minimizes vibration and energy spikes. Pump and Fan Control (PFC) adapts to changes in pressure, flow, or external data, improving process responsiveness and enabling energy savings across variable-torque applications. The drive also supports smooth starts and stops, reducing mechanical stress and extending motor life, while enabling stable operation in systems with fluctuating demand. Its compact LV drive design simplifies wiring and panel space, accelerating installation and retrofits. Compatibility with common industrial PLCs and HMI interfaces reduces commissioning time and supports scalable automation architectures.

FAQs
When retrofitting, ensure the drive is sized to the motor (25.4 A / 15 HP) and that the existing wiring supports LV drive integration. Verify panel space, clearance, and proper mains supply with correct filtering and protection. Plan for cooling, shielded communication cables, and a compatible PLC/HMI interface for seamless commissioning and monitoring. Use the built-in PID and PFC features to minimize downtime during commissioning and achieve rapid performance stabilization.
Built-in PID control provides closed-loop regulation of motor speed to match real-time demand, reducing overshoot and under-derating events. This leads to smoother pressure or flow control, lowers energy consumption, and minimizes thermal and mechanical stress on pumps and fans. In practice, you’ll see steadier operation in booster pumps and air handling systems with fewer need for manual tuning and external controllers.
The ACS310 is designed for variable-torque applications such as booster pumping systems and supply/return fans in HVAC. It’s well-suited for processes requiring precise flow control, energy efficiency through speed modulation, and easy integration with existing control platforms. Use cases include air handling units, water boosting, and other pump/fan assemblies where reliable VFD performance reduces cost and downtime.
The provided data does not list specific certifications. For project qualification, confirm CE marking for EU compliance and any site-specific IP ratings or SIL requirements with ABB’s datasheet or technical support. Always verify that the exact drive variant used in your installation matches your regulatory and safety requirements before commissioning.
ROI comes from energy savings due to reduced motor runtime, smoother operation with fewer surges, and lower maintenance costs from gentler starts. In variable torque scenarios such as booster pumps and HVAC fans, expect reductions in kW demand and improved system stability. ABB ACS310’s PID and PFC capabilities shorten commissioning time and enable scalable upgrades, further enhancing payback over the equipment lifecycle.
