Overview
The ABB ACS550 AC Drive (SKU: ACS550-U1-023A-4+B055+K454) is a high-performance variable frequency drive designed for demanding industrial applications. This 15 horsepower (11 kW) drive operates with a 23A rated current and supports a 3-phase input voltage range of 380-480V, making it compatible with standard industrial power systems. The drive is housed in a Type 12/IP55 enclosure, providing robust protection against dust, water, and harsh environmental conditions, ensuring reliable operation in challenging settings such as manufacturing plants, water treatment facilities, and food processing environments.
The ACS550 features advanced motor control capabilities with a 1.1 overload capacity, allowing it to handle temporary peak loads without interruption. It includes built-in PROFIBUS DP communication for seamless integration into automated control systems, enabling real-time monitoring and precise process adjustments. The drive’s compact footprint measures 22.1 x 8.4 x 9.6 inches (561 x 213 x 244 mm) and is designed for wall mounting, simplifying installation and saving valuable floor space in control rooms or machinery enclosures.
Optimized for energy efficiency, the ACS550 reduces power consumption by adjusting motor speed to match load requirements, which is particularly beneficial for applications such as pumps, fans, conveyors, and compressors. Its advanced control algorithms ensure smooth acceleration and deceleration, minimizing mechanical stress and extending equipment lifespan. The drive also supports multiple mounting orientations and includes integrated EMC filters for compliance with electromagnetic interference standards.
Manufactured in Denmark, the ACS550-U1-023A-4+B055+K454 is backed by ABB’s global service network, providing access to technical support, spare parts, and firmware updates. The UNSPSC code 39122001 classifies this product within the industrial automation category, confirming its suitability for a wide range of industrial drive applications.

FENA-21
The FENA 21 DualPort module supports Three protocols Modbus-TCP, EtherNet/IP, and the PROFInet IO RT network. The Modbus-TCP protocol is simply the Modbus protocol used on top of Ethernet-TCP/IP. Modbus-TCP is an open Industrial Ethernet network which has been specified by the Modbus-IDA User Organization. EtherNet/IP is based on the Common Industrial Protocol (CIP), which is also the framework for both the ControlNet and DeviceNet network protocols. PROFInet IO RT is an open network based on the PI Organization standard.
