ОПИСАНИЕ ПРОДУКТА
MITSUBISHI FR-BU2-H280K - Dynamic Braking Unit
This component is a dynamic braking unit from the MITSUBISHI FR-BU2 series, engineered to manage and dissipate regenerative energy generated by decelerating high-inertia loads in industrial applications. It connects to the DC bus of compatible MITSUBISHI FR-series variable frequency drives, preventing overvoltage conditions and enabling controlled, rapid deceleration. This unit is critical for systems requiring precise stopping and high-duty cycle braking, such as cranes, centrifuges, and material handling equipment.
