The ABB ACS355-03U-05A6-4 is a Compact Universal AC Drive (Variable Frequency Drive, VFD) from ABB's ACS355 series, rated for 2.2 kW (3 HP). It is specifically designed as a Single-Phase to Three-Phase Converter Drive, accepting a standard single-phase 200-240V AC input to power a three-phase induction motor. This makes it an ideal solution for applications in workshops, small factories, or commercial settings where only single-phase power is available.
