Compact, High-Performance General-Purpose Drive:The ACS355 series is ABB’s compact frequency converter designed for fans, pumps, compressors, conveyors, and other general industrial machinery, combining high performance with a small footprint—ideal for space-constrained installations.

Suitable for Medium-Sized Motors (1.1 kW):The “04A1” in the model indicates a rated output current of 4.1 A, capable of driving a 1.1 kW (1.5 HP) three-phase AC induction motor—perfect for small to medium-sized mechanical systems.

Built-in Brake Chopper for Fast Deceleration:This model includes an integrated brake chopper, allowing connection of an external braking resistor to enable rapid stopping and improved control in applications with inertia or frequent start/stop cycles.

Integrated C2-Class EMC Filter:Standard C2-class (industrial environment) EMC filter reduces electromagnetic interference, ensuring compliance with industrial EMC standards and simplifying system integration.

Wide Input Voltage Range (380–480 V AC):Supports 3-phase industrial supply voltages, compatible with global power systems, and ensures stable operation under voltage fluctuations.

Flexible I/O and Communication Support:Equipped with digital inputs (DI), relay output (RO), analog input (AI), and supports Modbus RTU protocol for seamless integration with PLCs, HMIs, and SCADA systems—enabling remote monitoring and automation.
