Product Description:
The TVM 2.2-50-300-W1 is a power supply module built by Bosch Rexroth Indramat and assigned to the TVM Power Supply Modules series. Within an automation cabinet, it converts three-phase mains power into a regulated DC link that energizes multiple servo drives, so it serves as the central energy source for a motion system. By supplying a common bus for connected axes, it supports coordinated machine operation without requiring a separate supply for each drive. The unit belongs to configuration level 2 of the product family, which includes integrated bleeder resistors and axial-flow ventilation hardware for standard cabinet installation.
The module accepts a nominal input of 220 V and can deliver a momentary surge of 150 A for 300 ms to satisfy drive inrush or dynamic braking demands. Its internal rectifier and filter create a DC link potential of 300 V. That bus is stabilized by a bleeder chain rated for 450 W of continuous dissipation, while a separate peak rating of 10 kW handles rapid regeneration events. Control electronics draw 1.3 A from the built-in +15 V rail, and peripheral sensors can receive 8 A from the 24 V auxiliary output. The housing has an IP10 rating, so the module is intended for installation inside a grounded enclosure. Separating the control and auxiliary rails also allows the module to support logic functions and external sensing devices while maintaining the main DC bus.
The thermal design keeps power losses, capped at 580 W, within limits up to 55 °C ambient with the help of a 30 W ventilation fan. Reliable service is permitted up to 1000 m of mounting altitude without derating, and energy returned from connected axes may reach 14 kWs before the bleeder circuitry reaches saturation. A 15 kW type-power classification aligns the supply with mid-frame Indramat drives that regenerate frequently yet remain below the peak capability envelope. Total mass is 15 kg, which supports slide-in cabinet installation while preserving the clearance needed for exhaust airflow. Fan-assisted airflow is especially useful in dense cabinets where neighboring drive modules add heat near the supply section.
