Product Description:
The TVM 2.1-050-W1/220 is a power supply module manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. It occupies a dedicated slot in a Rexroth drive cabinet. The module delivers a regulated DC bus for multiple servo amplifiers, allowing coordinated motion and energy recovery during dynamic braking in automated machinery. This shared supply arrangement supports multi-axis systems without requiring a separate supply stage for each amplifier.
The module accepts a nominal mains supply of AC 220 V (±15%) and rectifies it to a bus voltage of DC 300 V (±15%). Within this range, it can furnish a continuous output of 25 A while momentarily supplying a peak of 150 A for 300 ms to start or decelerate heavy axes. Overall power capability is rated at 15 kW. Internally, the unit has a type current of 50 A and includes a 15 V auxiliary rail that supplies 0.9 A for logic loads. A 0.45 kW bleeder resistor dissipates regenerated energy when the shared DC link cannot absorb it, and a 30 W ventilation fan helps keep thermal conditions stable. Continuous operation produces power loss that must be removed by cabinet airflow.
The design suits ambient temperatures up to 55 °C and mounting elevations not exceeding 1000 m without derating. Regenerated load peaks of 14 kWs are tolerated before the system returns to steady-state operation. Cabinet ingress protection is limited to IP10, so the module is intended for use inside closed electrical enclosures. Maximum internal dissipation is limited to 580 W, which affects panel cooling calculations. Mechanical data include a mass of 15 kg, a single-position configuration code of 1, and Series 2 classification. Ventilation power is allocated separately so the fan circuit remains energized even when the main DC link is unloaded.
