Product Description:
The TVM 1.2-050-W0 power supply module is produced by Bosch Rexroth Indramat and belongs to the TVM Power Supply Modules series. As a regulated supply, it rectifies plant mains and maintains a stable DC link for compatible Indramat drive controllers. An internal bleeder dissipates regenerated energy returned from braking axes, so the shared bus can remain within its intended operating range during deceleration. The unit is built for multi-axis drive cabinets, and its series 1 construction with configuration code 2 suits industrial automation systems where several axes operate from a common power source.
The electrical interface is aligned with common European factory mains. It receives AC 220 V from a three-phase line at 50-60 Hz, which makes it suitable for standard industrial supply networks. After rectification and filtering, the module delivers a stabilized 300 VDC bus to connected servo inverters. For continuous motion tasks, it can supply 25 A of output current, while its 50 A type current indicates permissible short-term surge capacity. This arrangement supports shared DC-bus operation when several connected axes accelerate, run, and decelerate on the same supply module.
Thermal management relies on natural convection, so cabinet airflow around the housing should remain unobstructed and the mounting space should allow heat to rise away from the module. The built-in bleeder resistor continuously dissipates up to 0.30 kW of regenerative power to help prevent DC-link overvoltage during braking events. During start-up or line disturbances, the supply can momentarily tolerate a mains current of 20 A, which matches the stated peak input demand for the unit. The module has a mass of 14.83 kg, giving it a solid panel-mounted form without calling for additional bracing in typical drive cabinets.
