ABB ACS55-01N-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 ACS55-01N-04A3-2 is a compact and practical AC variable frequency drive (VFD) designed for simple speed control of three-phase AC motors from a single-phase mains supply. As part of the reliable ABB ACS55 micro drive series, it is ideal for light-duty machinery, small automation systems and commercial motor control applications.
This micro drive provides straightforward motor speed regulation in a compact IP20 format, helping improve energy efficiency, process consistency and motor performance. The ACS55 series is designed for quick installation and intuitive configuration, making it suitable for OEM machine builders, installers and maintenance engineers.
With a rated output power of 0.75 kW and a single-phase 200–240 V AC supply, the ACS55-01N-04A3-2 is suitable for fans, conveyors, automatic gates, solar trackers, treadmills, whirlpool baths and other small motor-driven systems. This model is supplied without an EMC filter, making it suitable for installations where external filtering or specific panel arrangements are required.
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, improve comfort and provide smoother operation compared with fixed-speed motor control.
The ACS55 series is designed for applications where compact size, simple wiring and dependable operation are important. Its practical setup method and small footprint make it a convenient choice for retrofits, small machines and basic automation systems.
