Product Details:

The SEW BPS10-200-20-40-P-710 braking resistor is an external dynamic braking resistor specially matched for SEW MOVIDRIVE MDX61B, MD60A and MOVITRAC B series drives, used to consume regenerative energy generated by asynchronous and servo motors during deceleration, emergency stop and lowering movements. It has a resistance value of 200 ohms and a continuous power rating of 10kW, with strong short-term overload capacity to handle frequent four-quadrant working cycles. The suffix -P indicates it is equipped with an integrated built-in thermal protection switch, which can output over-temperature alarm signals to the drive control terminal for interlock protection, preventing permanent burnout of the resistance core under continuous heavy braking cycles.

This resistor adopts high-temperature alloy resistance wire winding structure and metal casing with air convection heat dissipation design. It can withstand high thermal shock and has stable resistance value under repeated energy impact. It is connected to the braking chopper terminal of the SEW inverter, and the built-in thermal contact will trigger the protection signal once the internal temperature exceeds the safe threshold. Built-in monitoring logic of the drive will detect the loss of thermal signal and braking circuit fault. If the resistor winding burns open, short-circuits or the thermal switch fails, the DC bus voltage of the drive will surge sharply during deceleration, and the system will report overvoltage alarm and cannot complete fast braking.

This braking resistor adopts IP20 protection grade, suitable for cabinet installation. It is equipped with heavy-duty power terminals and signal terminals for wiring connection with the braking unit and drive I/O port. The working ambient temperature range is 0℃ to 55℃, and the storage temperature range is -20℃ to 70℃. The surface of the resistor shell will reach high temperature during operation, so sufficient heat dissipation space must be reserved around it during installation, and it should not be covered by cables or other components.

This SEW BPS10-200-20-40-P-710 braking resistor is widely used as maintenance replacement spare parts for heavy-duty conveyors, packaging machines, lifting equipment, printing machines and other automation equipment that require stable four-quadrant braking control. Most spare parts circulating in the global industrial spare parts market are fully tested refurbished units. Before installation, technicians need to check the shell for deformation and burning traces, measure the resistance value and the continuity of the built-in thermal switch with a multimeter. After wiring, perform deceleration running test to verify bus voltage stability and thermal protection response. Regular cleaning of dust accumulated on the heat dissipation shell and inspection of terminal tightness can effectively reduce the risk of overheating damage and extend the service life of the resistor and supporting drive system.
