The ABB ACS355-03E-04A1-4 is a compact 1.5 kW variable frequency drive for three-phase 380 to 480 VAC motor systems. With a rated output current of 4.1 A, it is intended for smaller machinery axes and process equipment requiring adjustable motor speed, controlled acceleration, and repeatable operation.
This R1-frame drive is well suited to compact electrical cabinets where installation space is limited. It is used to regulate standard AC motors in equipment such as small conveyors, pumps, fans, feeders, mixers, and light material-handling systems.
Unlike a servo amplifier or PLC controller, the ACS355-03E-04A1-4 is a single-motor AC drive. Its main role is to vary motor speed and support controlled motor operation within a machine or process system.
