R911228647
Produced by Bosch Rexroth Indramat, the R911228647 (TCM 1.1-04-W0) is a supplementary capacitance module with an auxiliary capacitance of 4 mF. This device's purpose is to accumulate energy for use during acceleration, weighing roughly 6 kilograms. For efficient cooling, it employs natural convection, with an air inlet located on its bottom and an outlet on its top. Bosch specifies a minimum of 80 millimeters clearance on both top and bottom of the module to facilitate optimal airflow. The dimension of the module is 208 x 355 x 100 millimeters. For power connections to the module, it is advised to use a wire size up to the maximum of 6 mm2. The maximum recommended stud torque is 2.5 Nm.
The R911228647 (TCM 1.1-04-W0) is an auxiliary for power supply modules, primarily used for powering Indramat AC drives. In instances where transformer power exceeds 10 kVA, additional capacitors, like the R911228647 (TCM 1.1-04-W0), and soft start resistors control inrush current. Multiple drives can be powered from a single supply module, providing DC voltage for motor power and control voltages for connected drives. The power rectifiers in the power supply convert the three-phase in voltage, resulting in a DC voltage output for the drives. Power supply input voltage ratings are either 230 / 400 Volts AC or 115 / 230 Volts AC.
