ABB ACS355-03E-04A1-4 Inverter Drive

ABB ACS355-03E-04A1-4 Inverter Drive delivers approximately 1.5 kW (2 HP nominal, 460 V) of output for 380–480 V AC, three-phase motors, with a rated current of 4.1 A to support compact variable-speed control in industrial equipment. It supports programmable frequency from 0 to 500 Hz and offers scalar (V/Hz) and sensorless vector control for precise speed regulation. The unit features IP20 enclosure protection and can be mounted on a DIN rail or panel, with built-in EMC filter and braking chopper (model dependent) and an operating temperature range of 0 °C to +40 °C (higher with derating). Common applications include conveyors, packaging machinery, mixers, and pumps, as well as material handling, HVAC, food and beverage processing equipment, printing machinery, and other small automation machines where reliable motor speed control improves efficiency and reduces wear.
