The FR-AF740-06830-EC inverter by Mitsubishi is a sophisticated device intended for substantial motor control applications. With support for a motor capacity of up to 280 kW, this inverter is optimized for a variety of uses in industrial settings. It features a rated capacity of 417 kVA and is designed to manage a rated current of 683 Amps effectively.

When operating under overload conditions, the inverter allows for 110% current for a duration of 60 seconds, alongside a peak of 120% for 3 seconds in ambient temperatures up to 40°C. This flexibility ensures that the inverter can accommodate transient demands in high-performance applications. The voltage input range supports three-phase connections between 380 to 480 Volts AC, facilitating its integration into existing systems.

The inverter exhibits continuous regenerative torque of 10%, enabling enhanced energy recovery and efficiency during operation. However, it does not include a brake transistor. Weighing in at 175 kg, the FR-AF740-06830-EC requires an open-type enclosure, allowing for sufficient airflow. It operates with a forced air cooling system for thermal management. Note that a fan is not included in this model, which may be a consideration for system design. This device adheres to U.S. specifications, ensuring compatibility with relevant standards in operational contexts.
