Product Description:
The TVM-1.2-220/300/W1/220/380 is a power supply module manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. It delivers DC power and auxiliary low-voltage rails that feed multiple drive controllers in an automation rack. Design series 1 and configuration code 2 set its mechanical layout and connector arrangement. With a listed weight of 15 kg, the module can be panel-mounted without additional structural support. By centralizing rectification and auxiliary supply functions in one unit, it supports coordinated operation of several connected axes.
The incoming line voltage is rated at 220 VAC, and it is rectified and smoothed to a DC bus of 300 VDC for the connected drives. A power capability of 15 kW means the supply can continuously furnish that amount of electrical power to the motion system. Separate low-voltage outputs provide ±15 V at 0.85 A and a logic rail that can source 4 A at 24 V for control electronics, I/O, and sensors. The housing has a protection rating of IP10, so the module is intended for installation inside a closed control cabinet. Internally, 30 W of ventilation power is assigned to the cooling fans that move air across the heat sinks. The auxiliary outputs support control circuitry separately from the main DC bus, which helps keep interface electronics supplied during normal drive operation.
Dynamic braking energy from the inverters is absorbed by a bleeder resistor that handles a peak of 10 kW and a continuous load of 0.30 kW, which helps prevent overvoltage on the DC bus during rapid deceleration. For brief events such as emergency stops, the storage capacitors can take up to 14 kWs of feedback energy before the bleeder engages. Total thermal losses are capped at 550 W, so cabinet ventilation must be sized accordingly. The internal fans support airflow across the heat sinks and help maintain stable operation under full regenerative duty. This arrangement allows the supply to manage returned energy during repeated deceleration cycles from connected axes.
