Product Description:
The TVM 1.2-050-W0-220V is a power supply module produced by Bosch Rexroth Indramat within the TVM Power Supply Modules series. It converts a three-phase mains feed into a regulated DC bus so that multiple servo drives in an Indramat automation rack receive stable energy for motion, positioning, and spindle functions. Because the module supplies a common DC bus, connected drives can draw power from one central source within the rack. Version 1 hardware with configuration code 2 identifies its internal layout, while the 50 A type designation indicates the maximum bus current available during normal operation. An auxiliary 24 V logic output is present, and it is unregulated for circuits that do not require tight voltage tolerance.
The module is fed from an industrial supply of AC 220 V and uses a three-phase connection, allowing balanced line loading and lower ripple at the rectifier stage. After conversion, the unit presents a bus level of DC 300 V, which is the reference voltage supplied to connected drive controllers. At this level, the TVM can deliver up to 7.5 kW of continuous bus power, which is enough for several medium-frame servo axes operating at the same time. Output current is limited to 25 A under continuous duty so thermal and semiconductor stress remains within acceptable limits. An internal bleeder circuit dissipates regenerated energy and helps keep the bus voltage within its normal operating window. That behavior is useful when several axes return energy to the supply during deceleration.
The housing measures 22 cm in height, 62 cm in depth, and 42 cm in width, permitting cabinet integration beside servo drives without excessive rail usage. Gross mass is 14.83 kg, which affects panel support requirements when the module is mounted in a control cabinet. The chopper-controlled bleeder network is rated for 0.30 kW of continuous heat dissipation, so braking energy can be released without pushing the DC link above its intended range. During short overload events, the module can absorb returned energy from decelerating axes until the connected drives return to steady-state demand.
