{"product_id":"fuji-electric-bu220-4e","title":"Fuji Electric BU220-4E","description":"\u003cp\u003eThe Fuji Electric BU220-4E is an external dynamic braking unit (DBU) for the FRENIC-MEGA (G2) variable frequency drive (VFD). For drives above built-in braking transistor capacity, this unit manages regenerative energy from the motor to an external braking resistor, enabling controlled deceleration of large, high-inertia loads.\u003c\/p\u003e\u003cp\u003eMonitors the DC bus voltage and activates the braking resistor circuit when voltage rises above a safe threshold — during rapid deceleration or when the load overhauling the motor.\u003c\/p\u003e\u003cp\u003eRequired for large cranes, hoists, winders, and high-inertia fans. Must be paired with a compatible external braking resistor.
