ABB ACS550-01-023A-4 Variable Frequency Drive
The ABB ACS550-01-023A-4 is a high-performance Variable Frequency Drive (VFD) from ABB’s widely trusted ACS550 series, designed to optimize motor performance across diverse industrial environments. This VFD is an excellent choice for applications that demand precise control over motor speed and torque, such as pumps, fans, conveyors, and mixers, ensuring both energy efficiency and operational reliability.
Engineered for 3-phase, 380–480 V AC input at 50/60 Hz, the drive offers 11 kW (15 HP) output for normal use and 7.5 kW (10 HP) for heavy-duty use, backed by an output current capacity of 23 A and 15.4 A, respectively. It supports Scalar (V/f) and Sensorless Vector Control modes, delivering smooth operation and adaptability in various load conditions. The output frequency range extends from 0 to 500 Hz, catering to both standard and demanding motor control requirements.
This model supports 110% overload for 60 seconds in normal mode, and a robust 150% for 60 seconds in heavy-duty mode, enabling it to handle short-term surges with ease. Its IP21 (NEMA 1) rated enclosure makes it suitable for indoor, wall-mounted installations, while the fan cooling system maintains stable thermal performance. The compact dimensions of 469 mm x 125 mm x 222 mm and 8.52 kg weight make integration easy, even in space-constrained panels.
Among its integrated features, the drive includes a built-in EMC filter (Category C2), braking chopper, and Safe Torque Off (STO) for enhanced safety. A removable keypad with USB connectivity simplifies configuration, while the RS-485 Modbus RTU communication port supports flexible system integration. The drive is equipped with 6 digital inputs, 2 analog inputs, 2 analog outputs, and 3 relay outputs, ensuring comprehensive I/O interfacing for industrial automation systems.
Compliant with CE, UL, and cUL certifications, the ACS550-01-023A-4 stands out as a durable, smart, and efficient motor control solution that meets the reliability standards of modern industrial operations.
