The Bosch Rexroth R911230591 (TBM 1.2-40-W1/220) is a bleeder module from the TBM series designed for absorption and controlled dissipation of regenerated energy in automation systems. It operates in parallel with TVM power supply units and includes an integrated resistor and chopper circuit. With a bleeder power of 40 kW, it manages DC bus power from 11 to 60 kW and peak loads from 10 to 50 kW. During braking or generator operation, the module diverts excess energy from the DC bus, dissipating it as heat. Self-cooling is provided by a blower fan, ensuring stable operation and rapid discharge of filter capacitors on shutdown.
