Product Description:

Bosch Rexroth Indramat manufactures the TVM 2.4-050-220/300 115/200V as part of the TVM Power Supply Modules series. It is a power supply module with series code 2 and configuration 4. The unit supplies the intermediate DC bus for multi-axis drive assemblies, enabling coordinated acceleration and energy recovery in machining cells and assembly lines. By feeding a shared DC link, it allows several connected axes to draw from the same energy source during motion. With a type current capability of 50 A and a shipping mass of 15 kg, the module sits between the mains transformer and the individual servo inverters.

The incoming three-phase mains is rated at AC 220 V and may vary by +15 / -10% while still supporting 50/60 Hz operation. Inside the unit, the rectifier and smoothing network establish a nominal 300 V DC link that can deliver a continuous output current of 25 A. Corresponding bus power is sustained at 7.5 kW, and short bursts up to 60 kW are permitted for rapid motor torque demands during acceleration. Auxiliary rails provide 1.3 A at +15 V, 1 A at -15 V, and 8 A at 24 V for control electronics and brake release circuits. These auxiliary outputs support logic circuits, sensor interfaces, and related control functions without requiring a separate low-voltage source in the same cabinet.

Thermal and braking performance follow several additional limits. The converter draws a connection power of 550 VA from the upstream transformer, and the connected axes may continuously process 4.1 kW. Surplus regenerative energy is dissipated by an internal bleeder rated at 0.45 kW, and the energy storage network can absorb up to 14 kWs per braking event. This helps control bus voltage rise when decelerating axes return energy that is not used elsewhere in the system. For isolation, the internal autotransformer is rated at 7.9 kVA, and all secondary voltages are maintained within ±15 % so sensors and control boards remain within allowable thresholds during supply dips or swells.
