FRA560L800KNA

Mitsubishi's FRA560L800KNA inverter, classified as a large-capacity type, is engineered for high-performance applications. With an operating voltage of 575V and integrated for 3-phase use, this inverter is adept at managing input and output voltages at the same level of 575V across a frequency spectrum from 50 to 60 Hz. The device complies with stringent voltage and frequency tolerances, functioning effectively within parameters of 488 to 632V while tolerating variations of ±5%.

Control over the inverter is achieved through an advanced PWM system incorporating flux vector control, allowing precise regulation over a frequency range of 0.2 to 400 Hz. Regarding frequency accuracy, the unit maintains a tolerance of ±0.2% in analog mode and a much tighter ±0.01% in digital mode. The inverter accommodates adjustable voltage and frequency settings from 0 to 400 Hz and offers selectable CT/VT configurations.

The 150% starting torque capability at a low frequency of 0.5 Hz allows for effective starting under heavy load situations, which is essential in industrial environments. A forced air cooling system ensures the device remains within operational temperature limits even under peak loads.

Manufactured in an open-type design with an IP00 enclosure rating, it is suited for clean environments with limited debris and moisture. The inverter can support motors up to 800 kW, translating to power ratings of 1100 HP for CT configurations and 1200 HP for VT configurations. Current ratings are also substantial, rated at 1100 A for CT and 1210 A for VT setups. Additionally, the inverter is designed with impressive overload capabilities, permitting up to 150% for 60 seconds and 200% for 0.5 seconds in CT modes, with a slightly lower overloading threshold of 120% maintained for 60 seconds in VT configurations. The FRA560L800KNA is a powerful, adaptable inverter tailored for rigorous industrial applications.
