Description
The Omron 3G3RX-A4185-E1F RX inverter drive is a high-performance frequency converter built for demanding industrial applications. With a capacity of 18.5 kW in heavy-duty (38 A) and 22 kW in normal-duty (43 A) operation, it provides reliable power and precise motor control for pumps, compressors, conveyors, fans, and other heavy industrial machinery.
Supporting both open loop and closed loop vector control, the RX series ensures excellent torque stability and precise speed regulation across a wide range of applications. Its integrated braking resistance improves dynamic performance, enabling rapid deceleration and safe operation in high-demand processes.
The inverter is designed for three-phase 380 – 480 V input with a maximum output frequency of 400 Hz, suitable for both induction and permanent magnet motors. It also supports 4-quadrant operation, allowing regenerative control when paired with optional modules.
Compact and robust, with dimensions of 390 × 190 mm (H × D) and weighing 14 kg, the RX drive is panel-mountable and carries an IP20 protection rating, making it ideal for industrial environments.
