TVM 1.2-050-220/300-W1/220/380V

The Bosch Rexroth Indramat TVM 1.2-050-220/300-W1/220/380V is a robust power supply module from the TVM Power Supply Modules series, designed for modular Indramat AC drive systems. This unit operates with an Input Voltage of AC 220V and delivers a Bus Voltage of DC 300V, while providing a Type Current of 50 A. As a second-configuration power supply, its primary function is to convert incoming three-phase AC power into a stable DC-link voltage, enabling multiple drive controllers to operate seamlessly from a single source.

In detailed technical terms, the TVM 1.2-050 model generates a continuous DC bus power output of 7.5 kW and can handle peak power bursts up to 60 kW. During regenerative operation, it feeds back between 0.45 kW and 2.25 kW into the electrical system, enhancing overall energy efficiency. Operating at a nominal bus voltage of 300 V DC and rated for a continuous current of 50 A, this module incorporates both a transformer and an auxiliary bleeder module to maintain voltage stability and protect against overloads.

For additional reliability, the module features a built-in blower unit that draws external air for cooling, rated for AC 220–400 V at 50/60 Hz. Weighing approximately 15 kg, it is suitable for installation in ambient temperatures from +5 °C to +45 °C (with a maximum of +55 °C), and at altitudes up to 1000 m above sea level. The enclosure is rated IP10 for protection against foreign objects and accidental contact. By consolidating multiple drive feeds into one efficient power stage, the TVM 1.2-050-220/300-W1/220/380V enhances system compactness, reduces wiring complexity, and promotes energy regeneration, making it an ideal choice for demanding industrial automation applications.
