ACS355-03E-05A6-4 ABB Variable Frequency Inverter 400/480 VAC 0.75-630KW
ACS355-03E-05A6-4 Description
The ACS355-03E-05A6-4 is a compact, high-performance machine-type AC variable frequency drive from ABB, designed for precise speed control of three-phase induction motors in small to mid‑range industrial machinery. It operates on 3‑phase 380–480 V AC input with a rated output current of 5.6 A, suitable for 2.2 kW (ND / Normal Duty) and 1.5 kW (HD / Heavy Duty) motors. Featuring built-in RS485 Modbus, user-friendly programming, robust EMC design, and compact book‑style construction, it is widely used in material handling, packaging, textiles, food processing, and small machine tools.
