Product Description:
The TVM 2.2-050-W1-220/380 power supply module is produced by Bosch Rexroth Indramat as part of the TVM Power Supply Modules series. Designed for multi-axis drive packages, the unit converts mains voltage into a regulated DC link and dissipates regenerated energy so that servo amplifiers remain within safe voltage limits. In industrial automation cells, it serves as the central source of controlled DC power for coordinated motion in machine tools, printing lines, and material-handling equipment.
At a nominal input of 220 VAC, the module generates a stable bus of 300 VDC. During continuous duty, it supplies up to 25 A, while a short-term peak of 150 A is allowed for 300 ms to cover acceleration events. The type code also includes a 50 A rating that indicates the module's thermal design limit, and overall power handling reaches 15 kW to match the 050 designation. Excess kinetic energy is routed to an internal bleeder resistor that can absorb 450 W continuously, helping prevent overvoltage when motors decelerate. A dedicated 30 W ventilation fan maintains airflow through the enclosure, and total conversion losses are limited to 580 W so cabinet heat output can be estimated more easily.
The supply is configuration 2 within series 2 and weighs 15 kg, which supports mounting in upright panels. Control electronics receive auxiliary rails of plus 15 V at 1.3 A and minus 15 V at 1.0 A, allowing external sensors or logic cards to operate without additional supplies. The maximum feedback energy is 14 kWs; above that value, additional braking devices are required. Operation without output derating is permitted up to 55 °C, and personnel protection corresponds to enclosure code IP10, meaning finger-safe openings with no protection against dust or water. During short braking events, the bleeder peak can reach 10 kW.
