Product Description:

The TVM 2.2-050-W1-115 power supply module is manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. It serves as the front-end energy interface in Indramat drive systems, rectifying the incoming AC supply and stabilizing a shared DC bus for multiple servo drives. The module also generates control voltages and provides dynamic braking support, which reduces the need for separate support hardware in the cabinet. This arrangement is suited to automated machining, packaging, and material-handling equipment that uses several coordinated axes.

The power section accepts 220 V AC, while a separate control input can use 115 V AC or 220 V AC for logic circuits. From this supply, the module delivers 300 V DC on the bus with a continuous output of 25 A, which corresponds to 7.5 kW of usable power. Short bursts of up to 150 A for 300 ms support acceleration demand, and a bleeder resistor rated at 10 kW handles regenerated energy with a 450 W continuous bleeder capacity. Internal thermal losses are limited to 580 W, and a built-in blower moves forced air across the heat sink inside the IP10 housing. Auxiliary rails also provide +15 V at 1.3 A and -15 V at 1.0 A for encoder and control circuits, while the type current of 50 A and configuration code 2 place the unit within the medium-frame TVM range.

The module can absorb up to 14 kWs of feedback energy during rapid deceleration before the bus voltage approaches shutdown thresholds. Its maximum power loss and 15 kg mass are suited to panel mounting in enclosed drive cabinets, and the housing can be installed without separate structural hardware in typical industrial layouts. Peak and continuous bleeder values show how much regenerated energy the module can dissipate during repetitive stop-and-go motion. The plus and minus 15 V outputs also eliminate the need for separate low-power supplies for connected control electronics.
