Product Description:

The TVM 2.1-050-220/300-W1/115/300 power supply module is built by Bosch Rexroth Indramat and belongs to the TVM Power Supply Modules series (hardware generation 2). As a dedicated component in multi-axis drive systems, it draws factory mains and delivers a regulated DC link to servo controllers. The device is classified by the manufacturer as a power supply module and provides a type power rating of 15 kW with a type current of 50 A, making it suitable for medium-sized machining centers and handling lines that require a central source of stabilized bus energy.

The unit accepts an input of AC 220 V at 50...60 Hz; the mains side can deviate +15 % or −10 % from nominal, while the internal circuits tolerate a separate ±15 % margin. A built-in blower forces cooling air across the heat sink, countering the 580 W of worst-case power loss. DC conversion generates a nominal bus of DC 300 V and supplies a continuous current of 25 A. For control electronics and sensors the module includes 24 V at 8 A, plus ±15 V rails that deliver 0.9 A on the positive side and 1.0 A on the negative side. Configuration 1 indicates a single bleeder set, rated for 0.45 kW continuous absorption, and the assembly satisfies IP10 protection when installed below the maximum altitude of 1000 m.

For short regenerative spikes the bleeder can dissipate 10 kW, and the DC link can pass a peak of 150 A for 300 ms while storing up to 14 kWs of feedback energy without overvoltage. Safe operation is maintained up to a surrounding temperature of 55 °C; above that value derating is required. The enclosure weighs 15 kg, allowing cabinet mounting without heavy reinforcement yet giving enough thermal mass for stable temperature rise. Together these limits define how the supply buffers braking energy, supports fast accelerations, and aligns with the environmental and mechanical constraints typical of factory automation cells.
