Designed specifically for lift operations, the Mitsubishi FRA72155K is a highly capable variable speed and frequency drive. This inverter supports an operational voltage range of 380 to 480 V AC, accommodating 400V, 415V, or 440V configurations. It has a rated current of 215 A, which effectively positions it for high-demand applications. The drive maintains a power output capability of 55 kW, translating to 75 horsepower.

This unit's output frequency adjusts from a minimum of 0.2 Hz up to 400 Hz, allowing for a broad spectrum of speed control. Vector control technology enhances its performance, ensuring accurate motor control and smooth operations in various conditions. The forced air cooling system integrated within the design supports optimal thermal management to maintain performance stability.

Protection against overloads, short circuits, and overvoltages is implemented, enhancing the system's dependability and safety in operations. The device is rated at IP00, indicating that it is not protected against moisture or dust, so it should be used in suitable environments. Regarding connectivity, the FRA72155K is compatible with the Modbus RTU communication protocol, ensuring seamless integration into networked control systems. It includes one analog output at 0-10 Vdc to facilitate monitoring and control tasks effectively.
