Product Description

Bosch Rexroth is known for its durable motion control products. The company's products are built using high-quality materials.

The TBM 1.1-20-W1/220V is a bleeder module produced by the company. The bleeder module is integrated into the automation line. The device is used to absorb the additional regenerative energy generated by the drives when they are run in generator mode. The system has a peak bleeder power of 20 kW. This bleeder module dissipates the additional energy from the system bus. The additional energy is dissipated as heat. The TBM 1.1-20-W1/220V consists of a chopper and a resistor. When a motor is braking and the motor’s inverter is run in regenerative mode, the bus voltage can rise and reach the threshold voltage. This is when the system’s chopper engages to bleed excess energy through the resistor. Because of this, the bleeder module prevents the voltage from rising above the threshold value.

The TBM 1.1-20-W1/220V is very suitable for safety applications. The device is connected in parallel with a high voltage power supply. The bleeder module discharges the excess electric charge that is stored in the filter capacitor when the connected devices are switched off. The device prevents operating personnel from receiving an electric shock. The leftover charges are discharged with the help of the TBM 1.1-20-W1/220V. This model can also be used as a voltage divider. This device is very suitable when a system needs to be supplied with two or more voltages. Besides acting as a voltage divider, this module can also be used as a voltage regulator. The device minimizes the difference between no-load voltage and full load voltage that improves voltage regulation.
