2. Key Selling PointsCompact General-Purpose Drive:The ACS355 series is ABB’s compact frequency converter designed for
fans, pumps, conveyors, and small machinery, offering high
performance in a small footprint—ideal for space-constrained
installations. Suitable for Small Motors (0.37 kW):The “01A2” in the model indicates a rated output current of 1.2 A, suitable for driving 0.37 kW (0.5 HP) three-phase AC induction motors—perfect for low-power speed
control applications. Built-in Brake Chopper for Dynamic Braking:This model includes an integrated brake chopper, allowing
connection of an external braking resistor to enable fast
deceleration and improved control in applications with inertia or
frequent stopping. Integrated C2-Class EMC Filter:Standard C2-class (industrial environment) EMC filter reduces
electromagnetic interference, ensuring compliance with EMC
standards and simplifying system integration. Wide Input Voltage Range (380–480 V AC):Supports standard 3-phase industrial supply voltages, compatible
with global power systems, and ensures stable operation under
voltage fluctuations. Essential I/O and Modbus RTU Communication:Equipped with digital inputs (DI), relay output (RO), analog input
(AI), and supports Modbus RTU protocol for easy integration with PLCs, HMIs, and control
systems.
