ABB ACS310-03E-02A6-4 General Purpose AC Drive

Overview

The ABB ACS310-03E-02A6-4 is a compact general-purpose variable frequency drive from the ABB ACS310 series, designed for variable-torque applications such as pumps and fans. This ACS310-03E-02A6-4 is rated 0.75 kW, 2.6 A continuous output current, with 380–480 VAC three-phase supply and built-in EMC filter. It integrates native PID control, PFC pump-fan control logic, pre-programmed anti-clogging pump cleaning function and Modbus RTU communication. It is widely deployed on process skids, water treatment systems, HVAC and simple conveyor axes as an energy-saving speed controller for asynchronous motors.

Features

The ABB ACS310-03E-02A6-4 is optimized for pump and fan variable torque loads.ACS310-03E-02A6-4 comes with an integrated EMC filter for compliance with industrial emission standards. Built-in PID regulator supports closed-loop control of pressure, flow and temperature without external controllers. PFC multi-pump sequence control function enables automatic pump rotation and standby management. Modbus RTU over RS485 interface for easy connection to PLC, DCS and monitoring systems. Programmable analog and digital I/O terminals, relay output and motor thermal protection. Selectable switching frequency from 4 kHz up to 16 kHz to reduce audible noise. IP20 enclosure, wall-mounted design, compact footprint for cabinet installation. Multiple protective functions: overcurrent, overvoltage, undervoltage, overheat, short circuit and motor stall protection. Compliant with CE, cUL, RoHS and global industrial drive standards.

Principle

The ABB ACS310-03E-02A6-4 converts fixed-frequency three-phase AC power into variable-frequency, variable-voltage PWM output to drive asynchronous motors. The internal control unit processes analog setpoints and feedback signals, executes PID or PFC logic, and adjusts motor speed dynamically to match process demand. The integrated protection circuits continuously monitor drive and motor conditions to stop operation under fault conditions.

Applications

The ABB ACS310-03E-02A6-4 is used for speed regulation of water pumps, booster pumps, supply and return fans and light-duty handling equipment on process skids, water treatment and HVAC systems. The ACS310-03E-02A6-4 is stocked as spare replacement for ABB ACS310 variable torque control loops.
