Product Description:
The TVM 1.2-050-W0-115V belongs to the TVM Power Supply Modules series manufactured by Bosch Rexroth Indramat. As a regulated power supply module, it feeds the DC bus for multiple drive controllers, allowing coordinated motion and spindle functions in industrial automation lines. The unit converts plant AC mains into stabilized DC power, serving as the energy interface between the facility electrical supply and the servo amplifiers that move machine axes. Using a shared bus source helps connected axes draw power from one central module instead of relying on separate conversion stages at each drive. This arrangement is useful in cabinets where several axes share one power section and require consistent bus conditions during operation.
The module is designed for an input line of AC 220 V at 50/60 Hz, and it supports dual-range control inputs of 115 V or 220 V for monitoring circuits. Internally, it delivers a continuous output of 25 A on a bus held at DC 300 V. For brief overloads, current can rise to 50 A, and the overall power capability reaches 15 kW. The logic supply includes a 24 V L rail at 4 A continuous and ±15 V M rails at 0.85 A each, and the housing has an IP10 protection class for installation inside a protected cabinet. The auxiliary rails support low-voltage control electronics and feedback-related circuits within the drive system.
Dynamic events such as rapid deceleration are absorbed by a peak current of 150 A for up to 300 ms, and excess regenerative energy is dissipated through a bleeder rated at 0.30 kW. A feedback capacity of 14 kWs helps shield the DC bus from voltage spikes during rapid energy return. Safe operation is permitted up to 55 °C ambient and 1000 m installation altitude. Configuration code 2 and series index 1 identify this build. The regulated bus and auxiliary outputs allow the module to supply both power-stage and low-voltage circuits within a coordinated drive system.
