The Mitsubishi FR-A740-01800-NA6 is a robust AC drive that functions as a variable-frequency inverter. Rated at a power level of 90 kW (or 125 HP), this unit is suitable for high-performance applications requiring reliable motor control. It is configured for three-phase operation and can handle input voltages between 380 and 480 VAC, with a corresponding output voltage within that range. This drive is designed to handle a maximum current of 180 A, allowing it to effectively manage significant motor loads.

The FR-A740-01800-NA6 features a cooling system with a fan, ensuring adequate temperature regulation during operation. This inverter supports an output frequency range from 0.2 Hz to 400 Hz, providing operators with variable speed control. The control method employed in this drive is vector control, enhancing performance by allowing precise motor speed and torque management.

Safety is a priority, and this model includes protections against overload, short circuits, and overvoltage, which minimizes the risk of damage to connected equipment. The enclosure has an IP20 rating, indicating protection from solid objects larger than 12.5 mm while maintaining ventilation. With the capability to operate at either 50 or 60 Hz input frequencies, this drive is versatile and well-suited for a range of industrial applications.
