FR-A540L-375K-EC

The FR-A540L-375K-EC inverter is part of Mitsubishi's FREQROL FR series. It is engineered to operate effectively within a 3-phase voltage range of 380 to 480 volts. The rated current is established at 722 A, making this unit suitable for significant power management. The inverter exhibits strong overload capabilities, handling 120% for up to 60 seconds and 150% for a quick 0.5 seconds, ensuring robust performance during demanding conditions.

In terms of cooling, the FR-A540L-375K-EC utilizes a forced air cooling method to maintain optimal internal temperatures. The design is an open type with an IP00 protective structure, suitable for environments where direct exposure isn't a concern. This inverter operates reliably up to a maximum altitude of 1000 meters and can tolerate an ambient humidity level of 90% relative humidity or less, provided the conditions are non-condensing.

Regarding frequency management, it offers a resolution of 0.01 Hz with a tolerable fluctuation of ±5%, allowing for precise control and adjustment. The analog input accommodates a variety of signal types, including ranges of 0 to 5 VDC, 0 to 10 VDC, ±10 VDC, and 4 to 20 mADC, enhancing versatility in its applications. The storage temperature range is from -20°C to +65°C, providing flexibility for various operational environments. Additionally, it withstands vibration levels of 5.9 m/s² (0.6 G) or less, which contributes to its overall durability in industrial settings.
