Product Description:

Bosch Rexroth Indramat builds the TVM 2.2-050-220/300-W1/115/220V, a power supply module in the TVM Power Supply Modules series. It converts factory mains energy into a stabilized DC bus that feeds Indramat drive controllers across automated machining cells, packaging lines, and material-handling stations. The module’s role inside an installation is to furnish constant voltage rails, controlled bleeder dissipation, and auxiliary logic power, allowing connected servo axes to maintain repeatable torque and safe braking.

The unit accepts an input of AC 220 V at 50 to 60 Hz, with a +15/−10% line swing and an additional ±10% internal voltage margin, so it can ride through supply dips common in large plants. A built-in blower forces air across heat sinks to manage the steady 130 W of power loss that accompanies continuous service. Under rated conditions, the module delivers a DC bus rated current of 25 A and supports up to 7.5 kW of continuous bus power at the nominal 300 V level. Auxiliary rails provide −15 V at 1.0 A, +15 V at 1.3 A, and +24 V at 8 A for control logic. The control electronics can be energized from either 115 V AC or 220 V AC and draw 550 VA. The module uses configuration 2 hardware, and its type current limit is 50 A. A continuous bleeder resistor rated at 0.45 kW dissipates excess energy during mild decelerations.

As mechanical braking events intensify, the TVM module can momentarily absorb up to 60 kW from the drives, while its internal bleeder path tolerates short bursts of 10 kW. A storage capacitor stack holds a maximum of 14 kWs of regenerated energy, preventing DC overvoltage trips during repeated deceleration cycles. Despite these transient demands, the enclosure weighs only 15 kg, permitting straightforward panel mounting and keeping floor loads low for multi-axis cabinets.
