Product Description

• Estimated Lead Time : 6 - 8 weeks.

• Manufacturer : Danfoss

• Part Number : 131B0591

• Product Type : Brake Resistor (External Dynamic Braking Unit)

• Compatible VFD Series : Danfoss VLT (Used with various drive models, often including the FC 300 series, depending on the power rating).

• Function : Dissipates regenerative energy (excess power) that is fed back from the motor into the drive's DC bus during deceleration or when the load is overhauling the motor (like a descending hoist). This prevents the drive's DC bus voltage from rising too high, which would trip the drive.

• Resistance Value : Typically specified as 20 Ohms (Exact value is determined by the specific VFD model and frame size it's designed to protect).

• Power Rating : Designed for specific continuous or high-cycle braking duties, matched to the size of the motor/drive.

• Enclosure : Usually a robust IP20 or equivalent metallic enclosure, designed for wall mounting external to the drive cabinet.

• Key Feature : Essential for applications requiring fast, repeated, or heavy deceleration of high-inertia loads.

• Product Net Weight : Approx. 1.8 Kg (1800 grams/3.97 lbs)

• Approximate Dimensions : A rectangular metallic enclosure with cooling fins.

• Shipping Weight : 3 Kg
