The FR-AF740-05470-EC is part of Mitsubishi's FREQROL FR-A7 series and serves as a versatile inverter solution for power management. It offers an open type enclosure suitable for various mounting configurations and environmental conditions. This unit is rated for a substantial power supply capacity of 329 kVA and supports a maximum motor capacity of 220 kW, proving effective for demanding industrial applications.

With a rated current of 547 Amps, the inverter can handle significant loads. Its voltage specifications range between 380 and 480 volts AC. It operates in a three-phase configuration, which is standard in many industrial settings. Overload protection is built into the system, permitting a current of up to 110% for one minute and 120% for three seconds at an ambient temperature of 40°C, ensuring reliability under high-load conditions.

The FR-AF740-05470-EC also provides regenerative torque capabilities, delivering a continuous performance level at 10%. However, it does not include a brake transistor or a fan in its setup. For effective thermal management, this inverter relies on a forced air cooling system, designed to maintain optimal operating temperatures during use. With a total weight of 175 kg, it is crucial to consider installation logistics when deploying the unit.
