Product Description:

The TVM 2.2-050-220/380-W1 is a cabinet-mounted power unit manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Positioned at the front end of an Indramat drive cabinet, it converts plant-level alternating current into a stable direct-current link that servo drive controllers require for synchronized motion tasks. By centralizing energy conversion, the device lets multiple axes draw from a common bus, simplifying wiring and improving overall system efficiency in automated machining cells, material-handling lines, and similar industrial environments.

Its electrical input is AC 220 V, a level common to many three-phase factory feeds, and the design tolerates 50/60 Hz so it can operate on either regional standard without modification. The unit also accepts line fluctuations within +15/-10%, which helps prevent nuisance trips when the supply rises or dips around nominal. After rectification, integrated heat sinks are cooled by a built-in air blower, which maintains component temperature while the unit delivers a continuous output current of 25 A to the shared DC link. This continuous current rating indicates how many drives can be powered at the same time and how much sustained load the installation can support.

Parameter coding identifies the unit as configuration 2, a wiring variant with a particular internal circuit layout and connector placement. For brief overload events, the hardware supports a type current of 50 A, allowing short bursts of additional energy when several axes demand peak torque at once. The unit is classified as a Power Supply Module, which shows that it furnishes regulated energy rather than drive control functions. The hardware is released under series 2, aligning its control electronics with other second-generation TVM components so that mixed installations remain electrically compatible.
