ABB ACS355-03E-02A4-4 Inverter Drive Three-Phase

The ABB ACS355-03E-02A4-4 Inverter Drive provides compact variable-speed control for three-phase motors in light-to-medium power installations, enabling precise speed adjustment without occupying excess control space. It accepts 380–480 V AC three-phase input and delivers up to 2.4 A of output current with a nominal power of about 0.75 kW (1 HP at 460 V). The drive's programmable 0–500 Hz frequency range, combined with Scalar (V/Hz) and sensorless vector control, supports both simple speed control and more responsive torque behavior. Encased to IP20, it can be mounted on a DIN rail or a panel, and it includes built-in EMC filtering and a braking chopper where model dependent. Typical installations span conveyors, packaging machinery, mixers, pumps, and other small automation equipment where space savings and motor-speed tuning matter, with broader use in material handling, HVAC units, food and beverage processing, printing machinery, and small manufacturing applications. Operating temperature ranges from 0 °C to +40 °C, with higher ratings possible under derating. This drive is commonly used for retrofit upgrades, replacement of failed VFDs, control panel expansions, and new machine builds; common replacements include ABB ACS150-03E-02A4-4, ABB ACS310-03E-02A4-4, and ABB ACS580-01-02A4-4.
