Product Description:
The TBM 1.2-40-W1/220V bleeder module is manufactured by Bosch Rexroth Indramat as part of the TBM Bleeder Modules series. It is installed on the DC link of drive systems to dissipate surplus regenerative energy that appears when motors brake or loads overrun, preventing damaging voltage rises inside the power section. By converting excess electrical energy into heat through an internal resistor stack, the module protects frequency inverters and servo drives and supports stable operation in automated machinery such as presses, handling robots, and packaging lines.
This model can absorb up to 40 kW of peak energy, indicating how much transient power the resistor can safely convert without exceeding its temperature limit. A dedicated blower driven at 220 VAC moves cooling air across the elements so the resistor can return to its baseline temperature between duty cycles. Control wiring is accommodated by terminals that accept conductors up to 2.5 mm², giving adequate cross-section for low-current gate signals or thermal contacts. Thermal management is enhanced by internal air cooling with a built-in blower, which eliminates the need for separate cabinet fans. The enclosure depth is only 105 mm, allowing placement on shallow back panels while maintaining internal airflow channels.
The housing rises to 390 mm in height, providing enough vertical space for the resistor grid, blower, and temperature sensors without crowding adjacent components. A minimum clearance of 80 mm above and below the unit allows exhaust air to exit freely and helps prevent heat buildup in the control cabinet. Power cabling up to 6 mm² can be landed on the main terminals to carry the higher DC currents associated with braking events, and the overall width of 208 mm fits standard 200 mm rail sections for easier layout in multi-axis drive enclosures.
