Mitsubishi Electric FR-A820-0.4K-1 Variable Frequency Drive

The Mitsubishi Electric FR-A820-0.4K-1 Variable Frequency Drive is a motor speed controller that adjusts the speed of AC motors by changing the frequency and voltage of the power supplied to the motor. Manufactured by Mitsubishi Electric, the FR-A820-0.4K-1 carries a specific model designation used to identify this unit within Mitsubishi’s lineup of drive products. As a variable frequency drive, it converts control inputs into a configurable motor output, enabling smooth acceleration and deceleration and enabling variable-speed operation for three-phase motors. This device is typically used in industrial automation environments where precise speed and torque control are needed to match process requirements. By regulating motor speed, the FR-A820-0.4K-1 supports control schemes that require variable-speed drives as part of a broader automation system. It is part of Mitsubishi Electric's FR-A820 product line of variable frequency drives.
