Product Description:

The TVM 2.4-050-W1-115 is a power supply module produced by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Designed for three-phase drives, it accepts an input of AC 220 V and converts it into a stabilized DC link for multiple servo controllers on a common bus. This arrangement lets several axes share one energy source instead of using a separate supply for each controller. With a mass of 15 kg, the module fits control cabinets without adding excessive load. Its role in industrial automation is to provide regulated energy and braking dissipation so connected drives can maintain stable torque and speed control during operation.

Its DC link is maintained at DC 300 V, allowing the module to deliver a continuous bus power of 7.5 kW and peak surges up to 60 kW during acceleration events. For connected axes drawing steady energy, the unit supplies a continuous output current of 25 A, while a separate 24 V logic rail provides 8 A for control electronics. This separation supports the control circuits without placing that demand on the main bus output. The internal bleeder network dissipates regenerated energy with a continuous capability of 0.45 kW, preventing overvoltage when motor loads decelerate. Additional ratings include 4.1 kW of continuous mechanical power, a type current of 50 A, and electronics power consumption of 550 VA, which guide cabinet protection, conductor selection, and heat removal during normal operation.

For short braking events, the bleeder can absorb up to 10 kW, and the storage capacitors can accept 14 kWs of returned energy before voltage rises to the shutdown threshold. This braking capacity helps manage regenerated energy from decelerating motors without forcing an immediate shutdown. Under rated loading, the module produces only 130 W of power loss, supporting panel temperatures up to 55 °C with free convection. Operation is possible without derating at elevations up to 1000 m, and the IP10 housing requires mounting inside a protected enclosure. Configuration code 4 and series version 2 indicate the module arrangement used for this unit.
