Product Description:

The TVM 2.4-050-110/220-W1/110/220 is a power supply module produced by Bosch Rexroth Indramat for the TVM Power Supply Modules series. It converts three-phase mains power into a stabilized DC bus that feeds multiple Indramat servo drives, providing coordinated energy management inside an automation cabinet. By combining supply, bleeder, and logic voltages in one housing, the device simplifies multi-axis cabinet layouts used in machining centers and material-handling systems. This arrangement also allows connected drives to share a common DC source during synchronized motion.

The unit delivers a continuous output of 25 A to the DC link, and its internal design series 2 with configuration code 4 matches compatible drives in the range. The type current rating is 50 A, which indicates the permissible short-term load before protective shutdown. For energy throughput, the module provides 7.5 kW of continuous DC bus power and can support peaks up to 60 kW during rapid acceleration cycles, while excess energy is dissipated by a built-in bleeder resistor. Thermal losses are limited to 130 W, and a built-in air blower guides cooling air through the heat sinks to keep components within their operating range. Control electronics draw 550 VA from the mains, and the IP10 enclosure is intended for mounting inside a closed cabinet where exposure to foreign objects is limited.

The auxiliary supplies furnished by the module include a +24 V logic rail that can source 8 A, with permitted ripple of 10 percent, and ±15 V reference rails kept within 0.1 percent ripple for analog circuitry. The continuous bleeder section absorbs 0.45 kW to handle regenerative energy, working with a storage capacity of 14 kWs. Operation is permitted up to a maximum ambient temperature of 55 °C and at installation altitudes not exceeding 1000 m. The low-ripple auxiliary rails support stable control functions in the connected drive system. With a mass of 15 kg, the module can be panel-mounted without heavy structural reinforcement and still fit compact machine layouts.
