The OMRON 3GJX-A4004 is a state-of-the-art micro AC drive engineered for simple yet reliable variable speed control of induction motors in light industrial processes. As part of the 3G3JX series, this 0.4 kW unit operates on a 400V three-phase input and delivers precise speed and torque regulation for applications such as small conveyors, mixing drives, and ventilation fans. Its compact design minimizes panel space while offering a full suite of protection features, including overvoltage, undervoltage, and overcurrent safeguards. The drive supports both digital and analog control inputs, along with Modbus RTU for seamless integration into PLC-based automation systems. With a rugged IP20 enclosure and ambient temperature tolerance from -10°C to +50°C, the 3GJX-A4004 ensures long-term operational stability in demanding factory environments.
