MITSUBISHI FR-BR-15K - Braking Resistor Unit
This unit is a dedicated external braking resistor designed for MITSUBISHI FR series variable frequency drives. It dissipates regenerative energy generated by decelerating motors, preventing overvoltage conditions on the DC bus and enabling rapid, controlled deceleration of high-inertia loads. Essential for applications requiring frequent stopping or dynamic braking, such as conveyors, centrifuges, and lifting equipment.
