FR-A540-22K

The FR-A540-22K from Mitsubishi's FREQROL FR series is engineered for controlling motors with precision and efficiency. This device is designed to operate within a temperature range of -10°C to +50°C, making it adaptable to various environmental conditions. With dimensions of 300 mm in width, 150 mm in depth, and 200 mm in height, while weighing 13 kg, it can fit into diverse setups with ease.

The inverter accommodates output frequencies from 0.2 to 400 Hz, offering flexibility for different applications. It is rated for a maximum power of 22 kW, with a rated current of 43 amps providing substantial drive performance. The input voltage requirements are between 380 to 480 V AC, supporting a three-phase power system for robust operational capacities. The device runs on a frequency of either 50 or 60 Hz, depending on the application.

For motor control, the FR-A540-22K utilizes either soft-PWM or high carrier frequency PWM control strategies, allowing tailored performance as necessary. Significantly, it delivers a starting torque of 150% at 0.5 Hz, benefitting advanced magnetic flux vector control applications. Cooling is managed through forced air, ensuring efficient heat dissipation during operation. Additionally, the protection rating of IP20 classifies it as enclosed, providing basic safeguards against dust and contact.
