Product Information
Extended Description
3AUA0000049493 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 and pump/fan control (PFC) automate process adjustments, delivering tighter regulation and reduced energy consumption. This translates to measurable efficiency gains and longer equipment life by avoiding excessive starts and stops. Applications include booster pumps and supply/return fans, where consistent pressure and flow are essential. Designed for variable torque applications like pumping and ventilation, the ACS310 adapts torque to demand rather than simply boosting speed. The result is smoother operation, lower motor current peaks, and improved grid compatibility. Use cases include HVAC duct fans and water-supply booster systems, where load varies with process conditions. With a 20 Hp rating and 34.1 A drive current, the module fits mid-size motor loads without needing external accessories, reducing upfront hardware and simplifying wiring. Energy efficiency is amplified by built-in PFC, helping to maintain favorable power factor and reduce utility charges in facilities with multiple drives. ABB’s LV drive architecture supports compact enclosure footprints and straightforward wiring, easing installation time and panel space requirements. The ACS310 is designed for easy integration with ABB’s motor-control ecosystem, offering streamlined commissioning, diagnostics, and maintenance workflows for reliable operation in mission-critical air handling and water systems.
