The Mitsubishi FR-A540-5.5K-EC stands as a versatile transistorized inverter and variable frequency drive, catering to a variety of applications. It is rated for three-phase input at 400 VAC and is capable of supporting an output power of 5.5 kW. This model boasts a rated capacity of 9.1 kVA and a nominal current of 12 Amps, making it suitable for significant operational demands.
This drive ensures reliable performance at altitudes up to 1000 meters above sea level and operates within a vibration limit of 5.9 m/s², adhering to JIS C 0040 standards. The input frequency supports both 50 and 60 Hz systems, while the output frequency can be adjusted between 0.2 and 400 Hz, allowing for refined motor control. Notably, the unit can deliver 150% starting torque at 0.5Hz, when employing advanced magnetic flux vector control techniques.
The environmental operating conditions for the FR-A540-5.5K-EC range from -10°C to +50°C, ensuring it maintains constant torque under varying temperatures. However, it is designed for indoor use only, where humidity levels should not exceed 90% relative humidity (non-condensing). It is critical that the surrounding environment be free from any corrosive or flammable gases, as well as oil mist, dust, or dirt. The weight of this unit is approximately 6 kg, making it lightweight for its type.
