Product Description:
The TVM2.1-050-220/300 power supply module is manufactured by Bosch Rexroth Indramat within the TVM Power Supply Modules series. Designed for multi-axis automation, the unit converts three-phase mains power into a stabilized DC link that feeds Indramat servo drives and regenerative braking circuitry. By supplying a common bus voltage, it coordinates energy distribution among interconnected drive controllers and manages return energy during deceleration in industrial motion systems.
Its electrical capability starts with a rated output of 50 A, allowing the module to support several medium-power axis drives simultaneously without derating. The internal capacitor bank maintains a DC link potential of 300 V DC, giving downstream inverters a steady reference for motor commutation. Overall power handling reaches 15 kW, which is the continuous power the rectifier and smoothing components can deliver to the bus. For short acceleration bursts, the supply can furnish a surge of 150 A for 300 ms, and this peak current capacity helps maintain bus stability during brief high-torque demand. Excess regenerative energy is dissipated through an integrated resistor stack that tolerates a momentary load of 10 kW, preventing the DC link from rising into overvoltage during deceleration.
In addition to the main bus supply, the TVM2.1 provides a 24 V auxiliary rail that can deliver 8 A for control electronics. The energy storage network can absorb up to 14 kWs of regenerative energy, matching typical braking events in packaging or printing machinery. Thermal limits are managed through convection channels and a dedicated blower that consumes 30 W. Operation is permitted at ambient temperatures up to 55 °C and at elevations up to 1000 m without derating. The IP10 housing, worst-case power loss of 580 W, and mass of 15 kg require sufficient cabinet airflow and secure mounting support.
