FAQs
The ACS550-U1-017A-6 is designed to drive 3-phase motors up to 15 HP (approximately 11 kW) with a continuous current rating of about 17 A. It provides reliable torque across varying loads, making it well-suited for mid-size applications such as pumps, fans, and conveyors in manufacturing and process environments. It supports standard industrial drives integration without oversizing the motor.
Installation is streamlined thanks to the IP21-NEMA1 enclosure, which is intended for indoor panel mounting. Use the Direct Connect wiring option to minimize field cabling and choose bottom or side conduit to fit your cabinet layout. Ensure proper ventilation and secure cable entries to maintain enclosure integrity and reduce the risk of dust or moisture intrusion during operation.
Yes. With a 15 HP output and 17 A input, the drive provides smooth speed control and ramping suitable for conveyor belts and pump systems. The Direct Connect option simplifies wiring to motors, while the 48–63 Hz range supports diverse line frequencies. This makes it a practical choice for process lines and material handling where variable speed improves efficiency and throughput.
The drive carries an IP21-NEMA1 enclosure rating, indicating protection suitable for indoor installations against dust and light moisture ingress. While not all regions require additional certifications, this enclosure rating plus the 48–63 Hz operation supports widespread deployment in standard industrial settings and aligns with common compliance expectations for industrial drives used indoors.
The ACS550-U1-017A-6 consolidates motor control functions into a single unit, simplifying commissioning and reducing wiring complexity. This leads to faster startup, lower installation costs, and easier maintenance planning. Over the lifecycle, improved motor efficiency and reduced downtime contribute to a favorable return on investment for mid-size automation projects in pumps, fans, and conveyors.
