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

Overview

The ABB ACS310-03E-02A6-4 is a compact variable frequency drive from the ABB ACS310 series, optimized for pump and fan variable-torque loads. This ABB ACS310-03E-02A6-4 has a rated power of 0.75 kW and a continuous output current of 2.6 A, with a three-phase 380–480 VAC input and an integrated EMC filter. It features native PID closed-loop regulation, PFC multi-pump control sequence, pump cleaning anti-clogging function and Modbus RTU communication. It is widely deployed on industrial process skids, water treatment, HVAC and light-duty conveyor systems for energy-saving asynchronous motor speed control.

Features

The ABB ACS310-03E-02A6-4 is purpose-built for square-torque pump and fan applications.ACS310-03E-02A6-4 is equipped with a built-in EMC filter to meet industrial emission requirements. Onboard PID controller enables direct pressure, flow and temperature closed-loop control without an external PLC. PFC pump-fan control supports automatic pump rotation and standby management. RS485 Modbus RTU interface allows simple connection to PLC, DCS and monitoring systems. Programmable analog and digital I/O terminals, relay output and motor thermal protection. Switching frequency adjustable from 4 kHz to 16 kHz to reduce motor acoustic noise. IP20 protection rating, wall-mounted structure for cabinet installation. Full protection functions: overcurrent, overvoltage, undervoltage, overheat, short circuit and motor stall protection. Compliant with CE, cUL and RoHS standards.

Specs

Device Type: AC Frequency Inverter Model: ABB ACS310-03E-02A6-4 Brand: ABB Series: ACS310 Rated power: 0.75 kW Continuous output current: 2.6 A Input: 3-phase 380–480 VAC Output frequency range: 0–500 Hz Communication: Modbus RTU EMC filter: Integrated Frame size: R1 Protection class: IP20 Product ID: 3AUA0000039627 Status: Genuine ABB standard drive spare part

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 setpoints and process feedback signals, executes PID or PFC logic and dynamically adjusts motor speed to match process demand. Integrated protection circuits continuously monitor drive and motor operating conditions and trigger shutdown actions when faults occur.

Applications

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