The R911234737 (TBM 1.2-40-W1-220/S100) is an auxiliary bleeder unit engineered to manage and control the voltage levels in TVM series power supply systems. It functions by discharging filter capacitors connected to the system, thereby preventing excessive voltage buildup. With a specified power handling of 40 kW, the unit operates parallel to TVM power supply modules, dissipating regenerative energy as heat via an integrated chopper and resistor assembly. The device supports continuous operation, facilitated by a blower fan for efficient thermal management. Technical specifications include a DC bus power range of 11 to 60 kW and peak power support of 10 to 50 kW, serving the primary role of absorbing regenerated energy and maintaining voltage regulation.
