Product Overview
ACS310-03E-48A4-4 is a low voltage frequency converter from the ABB ACS310 series designed for variable torque applications such as booster pumps, circulation pumps, supply fans, and return air systems. The drive operates on 380-480 VAC three-phase input power and delivers 22 kW output power with 48.4 A nominal output current.
The ACS310 series integrates dedicated pump and fan control functions including built-in PID control and Pump and Fan Control (PFC) logic. These functions allow the drive to automatically adjust motor speed according to pressure, flow rate, and process demand, helping reduce energy consumption and mechanical stress in HVAC and water treatment systems.
This model uses an R4 frame structure with IP20 protection and is commonly installed inside industrial control cabinets for building automation and process control applications.

FAQs
What applications is ACS310-03E-48A4-4 designed for?
This drive is mainly designed for pumps, booster systems, ventilation fans, and HVAC process control applications.
Does the drive support Modbus communication?
Yes. The ACS310 series includes integrated Modbus communication capability through RS-485.
Can the drive control motor speed automatically using pressure feedback?
Yes. The built-in PID controller allows automatic speed adjustment using external process signals such as pressure or flow.
Is this drive suitable for cabinet installation?
Yes. The ACS310-03E-48A4-4 is designed as a cabinet-mounted drive module with IP20 enclosure protection.
Engineering & Installation Guide
Install the drive inside a properly ventilated control cabinet and maintain sufficient airflow around the heatsink area. High ambient temperature can reduce long-term component reliability.
Separate motor output cables from analog signal wiring and communication cables to minimize electromagnetic interference in process instrumentation systems.
For pump applications using PID control, verify sensor scaling and feedback signal stability during commissioning to prevent oscillation or unstable motor speed regulation.
