Product Description:

The TVM 2.2-050-220/300-W1/115/220 is a power supply module built by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Within a multi-axis drive rack, it converts three-phase mains energy into a regulated DC link for servo inverters that run motion, positioning, or spindle axes on automated equipment. Its design places the rectifier, intermediate circuit, and monitoring electronics in one enclosure so connected drives receive stable voltage without a separate transformer stage. It is used where several axes share a common bus and need a single source of rectified supply power.

The module can deliver a continuous output of 25 A to the DC bus, while its type current peaks at 50 A during brief overloads caused by rapid acceleration. It accepts an input of AC 220 V and operates at 50-60 Hz, and incoming line variation is accommodated within +15/-10%. Internal components are cooled by a built-in air blower that moves air across the heat sink fins to protect the power semiconductors from excess temperature. Current sensors monitor the control and power sections and disconnect the supply if abnormal demand exceeds the allowed limit. That overload capability helps the common bus remain available when multiple axes accelerate at the same time.

The control electronics can be powered by AC 115 V or 220 V, which allows the module to fit cabinets that use different auxiliary voltages. The intermediate circuit is maintained at DC 300 V so downstream converters receive stable bus energy during normal operation. In this product line, the unit is identified as Configuration 2, which matches the mechanical guides and connector pinouts used for this version of the TVM supply. This makes the module suitable for systems where the logic supply and the power conversion stage are fed separately.
