Product Description:

The TVM2.4-050-200/300-W1/115/220 is a power supply module manufactured by Bosch Rexroth Indramat and assigned to the TVM Power Supply Modules series. Within an industrial automation rack, it delivers the regulated DC link that supports multiple servo or spindle drive controllers, enabling coordinated motion and spindle power from a shared energy source. The unit converts plant-level three-phase mains and low-voltage control power into a stabilized, high-capacity DC bus so connected axes receive consistent voltage during acceleration, steady-state running, and braking.

The module accepts a three-phase input of 3 × 220 V AC and internally rectifies it to a DC link held at 300 V DC. Under continuous operating conditions, the bus can deliver 7.5 kW, while short-term transients up to 60 kW cover rapid motor acceleration or simultaneous axis demands. Control electronics are supplied from an auxiliary mains tap and draw 550 VA, which is used for cabinet power-distribution sizing in the logic section. The module also has a continuous mechanical output capability of 4.1 kW and a specified power loss of 130 W, so enclosure airflow must remove the resulting heat. Cabinet dimensions of 355 mm in depth, 390 mm in height, and 105 mm in width help with panel layout, and the 15 kg mass supports rigid mounting.

An internal bleeder resistor continuously dissipates up to 0.45 kW and can absorb peaks of 10 kW, so regenerated energy from decelerating drives is converted into heat instead of causing overvoltage on the DC bus. The allowable stored energy on the bus is capped at 14 kWs, which helps limit excessive DC rise during emergency stops. A stabilized logic rail supplies external sensors and interface boards with 8 A at 24 V, reducing the need for a separate control-cabinet supply. This auxiliary output can power connected low-voltage devices that require a regulated source during normal system operation.
