Product Description:
Bosch Rexroth Indramat builds the TVM 1.2-050-W0-220 as part of the TVM Power Supply Modules series. The device is a power supply module that converts three-phase mains power into a regulated DC bus for multiple servo drives in industrial automation racks. By providing a common DC link, it allows connected drives to share regenerated energy and simplifies cabinet wiring in multi-axis systems. It is intended to supply several motion axes from one central source rather than requiring a separate mains section for each drive.
The module accepts a three-phase input at AC 220 V and rectifies it to a stable bus of DC 300 V. During continuous operation, it can source 25 A of output current, supporting axis groups whose combined demand stays within that limit. A bus capacity of 7.5 kW supports sustained motion loads, while a separate bleeder circuit dissipates surplus regeneration at 0.30 kW so the bus voltage remains controlled during deceleration. The internal type current rating of 50 A allows brief overload events without immediately exceeding the module's short-term capability. Configuration code 2 and series version 1 identify the module version used within the TVM range.
For short acceleration bursts, the DC link can rise to 60 kW peak, allowing high-inertia axes to draw energy without tripping upstream protection. Heat from the power semiconductors is removed by natural convection, eliminating fans and reducing service needs where clean airflow is available. The housing carries a protection class of IP10, so it guards against accidental finger contact but requires installation inside an enclosure that provides additional protection from dust and moisture. Mechanical size is 390 x 105 x 325 mm, so the cabinet must have enough depth for the housing and cable bends. The balanced three-phase input arrangement supports straightforward connection to plant distribution networks without special supply-side adjustments.
