Product Description:
The TVM 1.2-050-W1 power supply module is produced by Bosch Rexroth Indramat and belongs to the TVM Power Supply Modules series. It converts incoming AC power to a stabilized DC link that services multiple drive controllers, allowing coordinated motion and controlled regeneration in automated machinery. This unit is installed in cabinets where a dedicated source of regulated bus energy is required for servo axes and spindle drives.
The module accepts a nominal input of AC 220 V, and an input-voltage tolerance of ±15% allows operation on supply lines that drift from the nominal value. Internally, it rectifies and filters the line to a nominal bus of DC 300 V, again with a ±15% tolerance to accommodate fluctuating load conditions. A continuous output capability of 25 A supports several axes, while a type current of 50 A is used for thermal sizing during intermittent duty. For short bursts, the unit can deliver a peak of 150 A for 300 ms to cover acceleration or regenerative spikes. The typical power handling capacity is 15 kW, and the feedback-energy rating of 14 kWs indicates how much regenerated energy the shared DC link can absorb before external dissipation is required. Configuration code 2 and hardware series 1 identify the physical build, and insulation category C helps protect internal circuits from overvoltage stress.
Excess regeneration is continuously burned in a bleeder rated at 0.30 kW, which helps prevent DC-bus overvoltage without enlarging the cabinet. Reliable service is supported up to a maximum ambient temperature of 55 °C and at mounting altitudes not exceeding 1000 m above sea level. The housing has an IP 10 protection rating, so it limits contact with large objects but still requires enclosure mounting where dust or fluids are present. Humidity class F materials and insulation systems rated to category C help maintain dielectric strength in damp industrial settings.
