Product Description:

The TVM 2.4-050-220 is a regulated supply module manufactured by Bosch Rexroth Indramat and belongs to the TVM Power Supply Modules series. It converts line power into a stabilized DC bus that feeds multiple Indramat drive controllers and simultaneously dissipates regenerated energy through an integrated bleeder stage. The designation 2 indicates the second series generation, while the 4 identifies Configuration 4 within that generation. By housing rectification, energy storage, and protective functions in one enclosure, the unit simplifies cabinet wiring in automated machinery lines.

Operating with an input of AC 220 V, the TVM 2.4-050-220 maintains consistent bus voltage even when line conditions vary. The permitted network range of 50–60 Hz covers common utility frequencies worldwide, so no line-frequency conversion is required. Under continuous duty, the module delivers 25 A of output current to the intermediate circuit, which is sufficient for simultaneously powering several small to medium servo axes. Its internal capacitors and choke support a sustained DC bus capability of 7.5 kW, giving the connected drives steady voltage during normal acceleration and positioning cycles.

During rapid deceleration, the bus can momentarily handle 60 kW, and the TVM module shunts this peak energy through its semiconductor bridge and the installed discharge resistor. That resistor is rated for 0.45 kW of continuous bleeder power, allowing frequent dynamic braking without external load banks. For applications requiring higher line capacity, the module has a type current of 50 A, which is the maximum permissible mains rating before protective shutdown. Voltage sag immunity is supported by an input tolerance of +15/-10 % relative to nominal. The steel housing weighs 15 kg, so standard panel supports are adequate for vertical mounting inside control cabinets.
