The Mitsubishi FRA560L375KNA is a large-capacity inverter characterized by its high specifications and versatile control features. It operates within a three-phase output voltage of 575 V and can handle input voltages ranging from 488 to 632 V, functioning effectively at both 50 and 60 Hz. The inverter is capable of producing a frequency range from 0.2 to 400 Hz, providing a flexible performance envelope suitable for various applications.
One key feature of this model is its selectable control system, which includes options for Soft-PWM or high carrier frequency PWM. This enables fine-tuning of performance, allowing for optimal operation based on specific requirements. The inverter's design includes a robust starting torque of 150% at 0.5 Hz, achieved through advanced magnetic flux vector control, ensuring reliable start-up under load conditions.
Thermal management is addressed through a forced air cooling method, maintaining operational integrity within an ambient temperature range of -10°C to 40°C. For constant torque modes, this inverter can even function at temperatures up to 50°C.
The FRA560L375KNA is built with an open-type protective structure with IP00 and IP20 ratings, which requires consideration for environmental factors when selecting mounting locations. Its acceleration and deceleration settings are adjustable from 0 to 3600 seconds, allowing for either linear or S-pattern modes, so users can customize the response characteristics based on application needs.
Weighing approximately 490 kg (1078 lbs.), this inverter is designed for installation in industrial environments where large-capacity drives are needed for heavy-duty applications. The Mitsubishi FRA560L375KNA represents a robust solution for demanding motor control tasks across various sectors.
