ABB ACS355-03E-08A8-4 Variable Frequency Drive

The ABB ACS355-03E-08A8-4 Inverter Drive is a compact variable frequency drive designed to control three-phase AC motors up to approximately 4 kW. It accepts 380–480 V AC, three-phase input and delivers an output current rated at 8.8 A, with a power rating of about 4 kW (5 HP nominal at 460 V). The drive offers a programmable frequency range from 0 to 500 Hz and supports both scalar V/Hz control and sensorless vector control for varied torque needs. Its enclosure is rated IP20, and it includes built-in EMC filtering and a braking chopper (model dependent). Mounting options include DIN rail or panel mounting, and the operating temperature range is 0 °C to +40 °C (higher with derating). Common applications include conveyors, packaging machinery, mixers, and pumps in light industrial and OEM settings, as well as material handling systems, HVAC units, printing presses, food and beverage processing equipment, and small manufacturing machinery where precise motor control improves efficiency and process accuracy.
