TVM 1.2-050-220/330-W1/220/380V

The Bosch Rexroth Indramat TVM 1.2-050-220/330-W1/220/380V module is a robust addition to the TVM Power Supply Modules series, designed to deliver reliable DC power for industrial drives. Featuring a rated current of 50 Amps and an input voltage of 220 Volts AC (three-phase, 50/60 Hz), this unit converts incoming AC to a DC bus voltage of 300 Volts DC via its integrated rectifier. Housed in a durable enclosure with IP10 protection, the TVM 1.2-050-220/330-W1/220/380V serves as the primary source of motor power and control voltages for multiple connected Bosch drive modules.

Equipped with a high-performance blower cooling system, the TVM power supply module ensures efficient heat dissipation under continuous load. The control electronics voltage accepts 220/380 Volts AC to power internal monitoring circuits, while the vertical mounting orientation optimizes airflow and installation flexibility. Operating reliably within an ambient temperature range of 5 to 45 degrees Celsius, the module features automatic derating between 45 and 55 degrees Celsius and altitude-related derating from 1,000 to 5,000 meters. Extensive monitoring functions communicate via the signal bus voltage, allowing real-time status updates and fault reporting to connected drives.

Built for compatibility, the TVM module can feed multiple drive units and supports a range of accessories—bleeder resistors, capacitors, and dynamic braking contactors—to tailor energy management and braking performance. Optional autotransformers (floor or wall mount) enable adjustment of mains voltage to the module’s input requirements, while isolation transformers protect against ungrounded AC supplies. The IP10-rated housing and blower-assisted cooling contribute to enhanced durability and operational efficiency in harsh industrial environments. By delivering stable DC power, comprehensive monitoring, and modular expandability, the TVM 1.2-050-220/330-W1/220/380V significantly improves uptime and productivity in automated drive applications.
