ABB ACS55-01E-04A3-2 micro drive, a 0.75 kW single phase input AC variable frequency drive designed for simple motor speed control in light machinery, commercial equipment and automation applications.
The ABB ACS55-01E-04A3-2 is a compact and easy-to-use AC variable frequency drive (VFD) designed for simple speed control of three-phase motors from a single-phase supply. As part of the reliable ABB ACS55 micro drive series, it is ideal for small machinery, light automation and commercial applications where straightforward motor control is required.
This micro drive provides dependable motor speed regulation in a compact IP20 format, helping improve energy efficiency, process control and motor performance. The ACS55 series is designed for simple commissioning and practical installation, making it suitable for both OEM machine builders and maintenance engineers.
With a rated output power of 0.75 kW and a single-phase 200–240 V AC supply, the ACS55-01E-04A3-2 is suitable for fans, conveyors, automatic gates, pumps, treadmills, solar trackers and other small motor-driven systems. Its wall-mounted design and screw terminal connections support quick installation in compact control environments.
Variable frequency drives such as the ABB ACS55 control motor speed by adjusting the frequency and voltage supplied to the motor. This allows equipment to run at the required speed, helping reduce energy use and improve control compared with fixed-speed motor operation.
The ACS55 series is designed for simple applications where compact size, easy installation and dependable performance are important. Its integrated EMC filtering and practical connection layout make it a convenient choice for small automation systems and machinery upgrades.
