PRODUCT INFORMATION
Product Overview
The ABB ACS550-U1-023A-4 ACS550 AC Drive is a variable frequency drive designed for industrial motor control. This unit operates from a three-phase line supply between 380 and 500 V AC. It accommodates an alternating input line frequency ranging from 48 to 63 Hz. The drive outputs a three-phase voltage from 380 to 500 V AC to driven equipment. It maintains a continuous rated output current of 23 A.
This model features an R2 frame size designed for space-conscious electrical enclosure or wall mounting. It delivers a power rating of 15 HP, equivalent to 11.0 kW. The chassis includes an integrated housing rated to IP21 and NEMA 1 specifications. This enclosure protects internal electronics against vertical water drops and solid objects larger than 12.5 millimeters.
