PRODUCT INFORMATION
Product Overview
The ABB ACS550-U1-015A-4 is an ACS550 series AC drive for variable-frequency motor control. This wall-mounted unit supports a three-phase input voltage range from 380 to 500 V AC. It delivers a nominal rated output of 7.5 kW or approximately 10 HP. Nominal output current reaches 15.4 A across a supply frequency of 48 to 63 Hz.
For demanding industrial operations, the drive delivers heavy-duty output of 5.5 kW or 7.5 HP. Continuous heavy-duty rated current provides up to 11.9 A for demanding industrial machinery. The unit features an IP21 and UL Type 1 NEMA enclosure rating. This enclosure configuration supports clean, wall-mounted electrical cabinet environments.
