The Mitsubishi FR-A740-1.5K is a three-phase inverter designed for performance in various applications. It operates efficiently at a voltage range of 380 to 480 Volts AC. The inverter has a considerable weight of 3.8 Kg and provides a power supply capacity of 3 kVA, making it suitable for significant loads.

With its capability to deliver continuous regenerative torque of up to 10%, the FR-A740-1.5K ensures enhanced dynamic performance during operation. It is engineered to work with motors of up to 1.5 kW capacity.

The rated current for this inverter is 4 Amps, ensuring a robust supply even under varying loads. Additionally, it supports overload ratings that allow for temporary surges—150% for 60 seconds and 200% for 3 seconds at a surrounding air temperature of up to 50 degrees Celsius. This performance characteristic is vital for applications requiring temporary increased capacity without risk of failure.

Furthermore, the FR-A740-1.5K features a forced air cooling system to maintain optimal operating temperatures, although it does not come equipped with a built-in fan or brake transistor. Its open-type enclosure promotes accessibility for installations while ensuring conformance to U.S. specifications.
