2. Key Selling PointsCompact, 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.
