ABB ACS550-01-045A-4 3AUA0000012789 Frequency Converter

Product Introduction

The ABB ACS550-01-045A-4 (3AUA0000012789) is a reliable general-purpose frequency converter designed for stable and efficient AC motor speed control in industrial automation systems. As part of ABB’s well-established ACS550 series, it offers consistent performance, straightforward commissioning, and broad applicability across standard industrial drive requirements.

This model operates on a three-phase 380–480V supply and is widely used in applications such as pumps, fans, conveyors, compressors, and general industrial machinery. With a rated output power of 22 kW under normal duty, it provides sufficient capacity for medium-power motor control tasks while maintaining stable operational behavior.

The drive is designed with simplicity and practicality in mind. Its built-in control interface and intuitive parameter structure allow fast setup and commissioning, reducing engineering time during installation and maintenance. This makes it suitable for both system integration projects and equipment upgrades.

The wall-mounted structure ensures easy cabinet installation and space efficiency. With an IP21 enclosure rating, it is intended for use in controlled indoor industrial environments.

With a frequency range of 48–63 Hz and integrated motor protection functions, the ACS550 series helps improve system reliability, reduce downtime, and support stable long-term operation in industrial conditions.
