MITSUBISHI FR-ABR-H0.4K - Braking Resistor Unit
This unit is an external braking resistor designed for integration with MITSUBISHI FR series variable frequency drives (VFDs) rated up to 0.4 kW. It functions to dissipate regenerative energy generated by decelerating motors, preventing DC bus overvoltage conditions and facilitating rapid, controlled deceleration in industrial applications. This component enhances the dynamic braking capability of the VFD system, crucial for applications requiring precise stopping or frequent deceleration cycles.
