TBM 1.1-20-W1

The Bosch Rexroth Indramat TBM 1.1-20-W1 bleeder module is part of the TBM Bleeder Modules series, designed to manage and dissipate excess energy in regenerative drive systems. With a Peak Power rating of 10…50 kW and a DC Bus Power capacity of 11…60 kW, this module’s primary function is the absorption of regenerated energy from the TVR series power supplies. Its rugged design and compact footprint make it ideal for industrial environments where reliable energy management is critical.

This bleeder module integrates a precision-controlled chopper and a high-quality bleeder resistor, enabling efficient transfer of surplus voltage when the motor inverter switches into regenerative mode during braking. An inbuilt blower rated at 115 VAC ensures consistent cooling, maintaining stable operating temperatures. Compatibility with the manufacturer’s TVR series power supplies simplifies system integration, while close mounting of the bleeder resistor to the DC bus capacitors minimizes discharge time and prevents residual high voltages.

Additional features include internal air circulation for enhanced heat dissipation and a design that reduces load on the main power supply, supporting voltage regulation in the absence of active regulators. Safety is assured through controlled power dissipation in both ON and OFF states, preventing dangerous voltage retention. The TBM 1.1-20-W1 module is backed by a one-year warranty and can be shipped internationally. In industrial applications, this module delivers consistent performance, increased system reliability, and improved longevity of drive components by effectively managing regenerated energy.
