FRA560L450KNA

The Mitsubishi FRA560L450KNA model is a high-capacity inverter engineered to meet various heavy-duty motor control requirements. This inverter can support up to 450 kW for constant torque applications and 530 kW for variable torque applications. It has an impressive overload capability for demanding situations, allowing for 150% overload for 60 seconds or up to 200% for a brief 0.5 seconds under constant torque conditions. If working with variable torque, the overload capacity drops to 120% for 60 seconds and 150% for half a second.

It produces an output voltage of 575V with a three-phase supply at either 50 or 60 Hz, ensuring compatibility with various motor types. Precision control is crucial, and this inverter offers frequency accuracy of ±0.2% in analog mode and ±0.01% in digital mode. The base frequency can be adjusted between 0 and 400 Hz, making it flexible for constant and variable torque applications.

Through magnetic flux vector control, the inverter delivers a starting torque of 150% even at low speeds (0.5 Hz). Users can manually adjust the torque boost to fine-tune performance based on specific requirements. Its integration into processes is customizable, with acceleration and deceleration times configurable from 0 to 3600 seconds, supporting linear and S-curve profiles.

In terms of braking features, the DC dynamic brake functions with adjustable settings for frequency (0–120 Hz), duration (0–10 seconds), and voltage (0–30%), providing effective control during deceleration. Cooling is achieved through a forced air system, ensuring optimal performance under heavy loads.

Housed in an open-type (IP00 and IP20) protective structure, the inverter is designed to handle ambient temperatures ranging from -10°C to 50°C for constant torque and -10°C to 40°C for variable torque applications. Its substantial weight, at 500 kg (1100 lbs.), indicates its robust design for industrial settings.
