The ABB ACS320-03U-05A6-4 is an ultra-compact 5.6 Ampere, 2.2 kW (3 HP) variable frequency drive from the ACS320 micro drive series. Designed for basic speed control of three-phase AC motors in material handling and simple machinery, it is prized for its extremely small size and integrated, "all-in-one" design with a sealed keypad, making it ideal for space-constrained and harsh industrial panels.
