ABB 3AUA0000049470 LV AC drive module - Pn 1 Hp, 5.2 A
Part Number: 3AUA0000049470
Quick Summary
ABB 3AUA0000049470 LV AC drive module is designed to optimize variable torque control for pump and fan systems. Engineers often wrestle with energy waste and inconsistent system pressures when operating motors at fixed speeds. This drive family supports CE conformity and robust protection features to help ensure safe, compliant operation in demanding environments. By combining built-in PID controllers with pump and fan control, it automatically responds to changes in pressure and flow to stabilize processes, reduce energy use, and extend motor life. For procurement and maintenance teams, this translates into lower operating costs, faster commissioning, and smoother retrofits across existing ABB ACS310 installations.

FAQs
To install, mount the drive in a suitable enclosure, connect the 3-phase supply and motor leads, and configure the ACS310-03U-05A2-2 for a 1 HP motor with a 5.2 A current. Set basic parameters (motor type, rated voltage, acceleration/deceleration, and motor protection). Verify wiring integrity, perform a quick check of control wiring to the PLC or DCS, and commission using the built-in run/stop controls and PID/PFC features for pump/fan loads.
The module is rated for a nominal 1 HP motor with a current draw of 5.2 A. It includes built-in PID controllers and pump and fan control (PFC) to manage variable torque loads. It is designed for LV applications, with features tailored to maintain stable flow and pressure in booster pumps and HVAC fans, reducing energy consumption and wear compared with fixed-speed drives.
Yes. The ACS310 is specifically designed for variable torque applications, including booster pumps and supply/return fans. Its integrated PID and PFC capabilities allow automatic adjustments to changing pressures and flows, delivering energy efficiency, better process stability, and easier control in HVAC and water handling systems.
ABB designs the ACS310 family to meet common global standards, with emphasis on safety and reliability. Ensure your specific configuration includes CE conformity and verify any required IP protection or SIL ratings in the datasheet or with your ABB representative. Certification scope may vary by region and installation environment, so confirm before deployment.
The built-in PID and pump/fan control enable precise regulation of variable torque loads, reducing energy consumption during partial-load conditions and decreasing peak demand. Benefits include longer motor life, lower maintenance costs, and faster commissioning, contributing to a favorable return on investment in systems with fluctuating pump and fan demands.
