The Mitsubishi FR-A520-11K-NA operates within the 200V class and employs a transistorized inverter design. This unit is versatile at approximately 8.0 kg in weight due to its ability to switch between V/F control and advanced magnetic flux vector control. Designed for effective motor control, it supports an 11 kW capacity.

The device utilizes air cooling with forced ventilation, ensuring optimal thermal performance. Rated for 17.6 kVA, the inverter exhibits a rated output current of 46 A, allowing for substantial power handling. Furthermore, it has impressive overload capabilities—supporting up to 150% of its rated current for one minute and 200% for half a second, catering to transient conditions in industrial environments.

The inverter's input and output voltage capabilities range within three-phase configurations at 200-220V for 50Hz or 200-240V for 60Hz. This flexibility is essential for integration into various systems. Voltage fluctuations are acceptable within 170 to 242V at 50Hz and 170 to 264V at 60Hz, ensuring stable operations even under variable conditions. The frequency output spans from 0.2 to 400 Hz, facilitating a broad scope of motor speed control.

Operating within a temperature spectrum of -10°C to +50°C, this inverter is suitable for various applications, provided that non-freezing conditions are maintained. Moreover, users can configure acceleration and deceleration times from 0 to 3600 seconds, allowing fine-tuning of operational responsiveness to meet specific application requirements. The unit is housed in an IP20 enclosure, providing adequate protection against solid foreign objects.
