TCM 1.1-04-W0

TCM 1.1-04-W0, Bosch Rexroth Indramat, TCM Capacitance Modules auxiliary capacitance module is engineered to buffer regenerative energy in high-performance AC drive systems. This module features a TCM product designation in Series 1, Version 1 format, providing seamless integration with Rexroth Indramat power supply units. The TCM 1.1-04-W0 employs an on-board 4 mF Capacitor to store charge that can be rapidly released during acceleration or braking phases. A robust design ensures natural heat dissipation, making it suitable for continuous duty cycles in demanding industrial environments.

The module’s compact footprint of 208 x 355 x 100 mm and a total mass of 6 kg facilitate installation in space-constrained control cabinets. Cooling is achieved by Natural Convection, with a bottom cooling air inlet and top cooling air outlet, while Bosch recommends a minimum clearance of 80 mm above and below to maintain optimal airflow. Power connections accept up to 6 mm2 conductors, and the hardware supports a maximum stud torque of 2.5 Nm for secure wiring. All components are housed in a sealed enclosure that resists contamination and simplifies routine inspections.

As an accessory for Rexroth Indramat power supply modules, the TCM 1.1-04-W0 enhances system reliability by smoothing DC-link voltage and absorbing regeneration peaks. Its modular format enables multi-drive configurations, reducing overall footprint and wiring complexity. Ideal for packaging lines, robotics, and servo-driven machinery, this capacitance module delivers consistent performance and prolongs drive component life by limiting inrush currents and voltage spikes.
