Specification

The OMRON 3G3RX-A4370-E1F is a flagship model in the RX series of high-performance inverters, engineered to deliver exceptional motor control for demanding industrial environments. This 370 kW unit operates on a 3-phase 400V AC supply, featuring advanced sensorless vector control that ensures smooth torque output from zero speed to full rated speed. Its robust design includes a built-in DC reactor and EMC filter, minimizing electrical noise and harmonic distortion, which is critical for sensitive installations. The inverter supports multiple control modes, including V/f, open-loop vector, and closed-loop vector (with optional encoder card), making it versatile for applications ranging from simple speed control to complex process automation. With a wide operating temperature range (-10°C to +50°C) and protection features like overload, overvoltage, and phase loss detection, the 3G3RX-A4370-E1F guarantees long-term reliability in harsh conditions. The intuitive LCD keypad allows for quick setup and diagnostics, while optional fieldbus modules enable seamless integration into existing networks. Below is the detailed specification table for this model.
