Product Description:
The TVM 2.1-050-W1/115V is a power supply module built by Bosch Rexroth Indramat for the TVM Power Supply Modules series. The unit converts three-phase mains power into a stabilized DC bus and auxiliary voltages, providing centralized energy for Indramat drive controllers in factory automation lines. By supplying regulated power, it supports coordinated motion of servo axes, axis controllers, and their feedback electronics within a single cabinet. This arrangement allows multiple compatible drives to share one power source while keeping the cabinet layout compact.
Its electrical interface starts with a nominal input of 220 V AC (±15%), processed by an internal rectifier that maintains a bus level of 300 V DC (±15%). Under steady load, the module delivers a continuous output of 25 A, while the 50 A design rating covers transient duty and the available peak of 150 A for 300 ms supports rapid acceleration currents from connected drives. A maximum dissipation of 580 W sets the cooling load for the enclosure. Auxiliary rails include 24 V at 8 A for control logic and -15 V at 1 A for analog circuits, while the ±15 V line maintains a standing-wave ratio of 2%. Continuous bleeder power is 0.45 kW, allowing the module to absorb regenerative energy during motor deceleration. The unit is configuration 1 in Series 2.
The module operates at ambient temperatures up to 55 °C without derating and can be mounted at elevations reaching 1000 m above sea level. It can absorb up to 14 kWs of feedback energy during braking events, which helps manage short bursts of returned power from connected axes. The available output rating is 15 kW, which sets the power limit for the connected drive group. An IP10 housing provides basic touch protection, and the assembly weighs 15 kg, which helps keep cabinet mounting loads moderate.
