Product Details:

The SEW 199-189-2-25M brake resistor is a dedicated drive spare part designed by SEW-EURODRIVE for MOVITRAC and MOVIDRAC series inverters and servo drives. This braking resistor unit absorbs the regenerative energy fed back by the motor during fast deceleration or load overhauling, converts excess electric energy into heat energy and releases it, so as to suppress the DC bus overvoltage fault of the drive system. It matches the braking unit circuit of SEW drives, ensures stable deceleration and emergency stop for hoists, conveyors, cranes and other equipment with large inertia load. If the resistor wire breaks or insulation fails, the drive will trigger overvoltage alarms during deceleration and cannot stop the axis stably.

This braking resistor adopts metal shell enclosed structure, with built-in resistance wire and temperature protection switch. It is equipped with high-current wiring terminals for convenient connection with the drive braking terminal. It has good heat dissipation performance and insulation protection, suitable for cabinet external mounting layout. The rated working ambient temperature range is 0℃ to 55℃, and storage temperature ranges from -20℃ to 70℃. Thermal protection function can cut off the circuit automatically when overheating occurs to avoid burnout caused by long-time energy consumption.

This SEW 199-189-2-25M brake resistor is widely used as maintenance replacement spare parts for automated production lines, lifting machinery, packaging machines, material handling equipment and other inertia load equipment matched with SEW frequency converters and servo drives. The original manufacturer has discontinued this model, and most units available on the global industrial spare parts market are fully tested refurbished units. Before installation, technicians need to inspect resistance wire, insulation layer, thermal switch, wiring terminals and housing for aging, cracking and poor contact. After installation, users need to confirm correct wiring to the braking terminal, set braking duty cycle parameters, and check temperature rise during repeated deceleration tests. Proper matching and inspection of this brake resistor can effectively prevent overvoltage faults and ensure safe stop of the equipment, reducing unplanned production downtime.
