Mitsubishi's FR-A520-22K-NA is classified under the FREQROL FR-A5 series as a 200V inverter. This model maintains functional flexibility across a frequency range of 0.2 Hz to 400 Hz. Precision is paramount, with frequency accuracy reaching ±0.2% for analog inputs and an impressive ±0.01% for those using digital sources.
The inverter accommodates adjustable voltage and frequency patterns, making it ideal for constant or variable torque operations. With an output current of 90 A, it can manage significant loads effectively. Performance under stress is robust, featuring overload capacity metrics of 150% for up to 60 seconds and 200% for short bursts lasting 0.5 seconds.
The FR-A520-22K-NA operates on input voltages of 200–220V at 50 Hz or 200–240V at 60 Hz. The unit is also equipped to handle fluctuations in input voltage, remaining stable between 170 and 242V at 50 Hz and 170 and 264V at 60 Hz.
Acceleration and deceleration times can be programmed from 0 to 3600 seconds, with options for linear or S-curve profiles, enhancing user control over motor response. This inverter's cooling system is implemented through forced air to maintain operational integrity.
A DC brake is integrated, providing functionality within 0–120 Hz frequencies, with adjustable activation times up to 10 seconds and settings for voltage rates between 0% and 30%. The FR-A520-22K-NA has an IP20 enclosure rating, ensuring adequate protection from solid particulates. Operating temperatures span from -10°C to +50°C, extending its application range. Noteworthy is its starting torque characteristic, delivering 150% at 0.5 Hz through effective flux vector control. Engineered for motor capacities up to 22 kW, it stands as a competent choice for various industrial applications.
