FR-A540-30K

The Mitsubishi FR-A540-30K is part of the FREQROL FR series, recognized for its reliable performance in variable frequency drive applications. With a rated current of 57A, the unit operates efficiently on a three-phase supply voltage within the range of 380 to 480 volts AC. The frequency adaptable capability of this drive operates at either 50 or 60 Hz with permissible fluctuations of ±5%. Users can expect that the device handles voltage variations effectively, as it accommodates fluctuations from 323 to 528 volts.

Designed to offer versatility, the drive supports an output frequency spanning from 0.2 Hz to 400 Hz. For precise adjustments, frequency setting resolution is provided at 0.01 Hz, ensuring users can fine-tune output conditions according to specific operational requirements. The unit has a rated capacity of 30 kW, equating to approximately 40 HP, making it suitable for a range of applications.

The device also provides adjustable acceleration and deceleration times that can be set between 0.1 seconds to 3600 seconds, allowing for smooth transitions based on system demands. Furthermore, its lightweight construction (approximately 24 kg) aids in installation. The enclosure is rated IP20, which affords it protection from larger foreign objects but is not suitable for wet environments.

Lastly, the FR-A540-30K is equipped with multiple protective features to enhance reliability, including overcurrent, overvoltage, undervoltage, overload, and ground fault protections. These integral safeguards ensure that the drive operates within safe limits, thereby prolonging its service life and maintaining system integrity.
