ABB ACS55-01N-02A2-1 micro drive, product ID 68878390, a 0.37 kW single phase 110-120 V AC variable frequency drive for simple three phase motor speed control.
The ABB ACS55-01N-02A2-1, product ID 68878390, is a compact and reliable 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 provides an easy-to-install motor control solution for commercial, domestic and light industrial applications.
This micro drive is ideal for straightforward applications such as automatic gates, solar trackers, fans, conveyors, treadmills and whirlpool baths. The ACS55 series is designed to fit into small spaces and can be integrated into existing panels as an efficient replacement for contactors and motor starters.
With a rated output power of 0.37 kW, a nominal output current of 2.2 A and a single-phase 110–120 V AC input supply, the ACS55-01N-02A2-1 is suitable for controlling small three-phase 230 V AC motors. Its IP20 enclosure and compact footprint make it practical for protected control panel and machinery installations.
Variable frequency drives such as the ABB ACS55 regulate motor speed by adjusting output voltage and frequency. This allows equipment to run more efficiently, improves process control and reduces mechanical stress compared with fixed-speed operation.
The ACS55 micro drive range is designed for users who need straightforward speed control without complex commissioning. Its compact size, intuitive configuration and dependable performance make it suitable for OEMs, installers, panel builders and maintenance teams.
