£621.60
The ABB ACS380-042C-09A4-4 (Product ID: 3AXD50000031867) is a compact and highly reliable AC variable frequency drive (VFD) designed for precise speed and torque control in machinery and industrial automation applications. As part of the advanced ABB ACS380 machinery drive series, it offers seamless machine integration, flexible connectivity and dependable motor control performance.
Engineered specifically for machine builders and OEM manufacturers, the ACS380 includes built-in functionality such as an EMC filter, integrated safety features and adaptive programming capabilities. These features simplify installation and commissioning while helping improve machine performance, productivity and energy efficiency.
With a rated output power of 4 kW (VT / normal duty) or 3 kW (CT / heavy duty), a nominal output current of 9.4 A and a three-phase 380–480 V AC supply, the ACS380-042C-09A4-4 is ideal for conveyors, mixers, pumps, fans, packaging equipment and general industrial machinery. Its compact wall-mounted design enables easy installation within control panels and machine cabinets.
Variable frequency drives such as the ABB ACS380 regulate motor speed by adjusting output voltage and frequency. This allows machinery to operate more efficiently while improving process precision, reducing energy consumption and minimising mechanical stress on motors and drive components.
The ACS380 series is designed to simplify machine building through integrated functionality, extensive connectivity options and ABB's all-compatible drive architecture. This enables faster machine development and easier long-term maintenance.
