TVM 2.1-050-220/300-W1/115/220

The Bosch Rexroth Indramat TVM 2.1-050-220/300-W1/115/220 from the TVM Power Supply Modules series offers robust energy management in a compact footprint. Designed with a Configuration 1 topology and handling an Input Voltage of AC 220V, the module delivers a steady Bus Voltage of DC 300 while supplying up to 50A Type Current to connected drives. Its integrated power rectifier converts three-phase mains into a regulated DC bus, and the front-panel RESET button enables fast recovery after fault conditions. Modular wiring is simplified via the included wire-ribbon cable, ensuring seamless integration with Bosch Rexroth AC servo drives.

The TVM module’s comprehensive protection features include a control voltage fuse and two line-input fuses mounted on the bottom of the front panel, guarding against overcurrent events. A ready-state contact triggers the dynamic braking function during fault scenarios, safely decelerating connected motors to a standstill. The device supports a line voltage rating of 3 x 220VAC (+/-15%) or 3 x 230VAC (+10%/-15%), adaptable via an autotransformer for different supply environments. An onboard diagnostic display with LED indicators provides real-time status feedback, accelerating fault finding during commissioning and maintenance.

Energy efficiency is enhanced by the internal DC bus circuit, which stores regenerative energy for reuse during acceleration, reducing external braking resistor requirements. With a line code of 2 and design code of 1, this power supply conforms to industry standards for modular drive systems. Shipped with a one-year warranty, the TVM 2.1-050-220/300-W1/115/220 module ensures reliable power delivery and simplified integration for precision motion control applications.
