ABB 68878381 ACS55-01N-01A4-1 micro drive, a 0.18 kW single-phase input AC variable frequency drive designed for simple speed control of small three-phase motors.
The ABB 68878381, also known as ACS55-01N-01A4-1, is a compact and easy-to-use AC variable frequency drive (VFD) designed for simple speed control of small three-phase motors. As part of the ABB ACS55 micro drive series, it is ideal for light industrial machinery, commercial equipment and OEM applications where space-saving motor control and straightforward setup are required.
This micro drive is designed to improve small motor performance by providing variable speed control in a slim, panel-friendly format. Its simple setup using switches and potentiometers makes installation quick, while optional PC configuration through ABB DriveConfig supports more advanced commissioning when required.
With a rated output power of 0.18 kW, a nominal output current of 1.4 A and a single-phase 110–120 V AC input supply, the ACS55-01N-01A4-1 provides a variable frequency three-phase 230 V AC output for small AC motors. Its IP20 enclosure is suitable for DIN rail or panel mounting inside electrical cabinets.
Micro drives such as the ABB ACS55 regulate motor speed by adjusting output voltage and frequency. This enables smoother operation, improved process control and better energy efficiency compared with fixed-speed motor operation in suitable applications.
The ACS55 series is designed for straightforward installation in compact spaces. Its simple configuration method makes it particularly useful for OEM equipment, small machinery and applications where quick commissioning and dependable operation are important.
