Product Description:

The TVM 2.2-050-220/300-W1/220/380V is a power supply module manufactured by Bosch Rexroth Indramat for the TVM Power Supply Modules series. Installed in central control cabinets, it rectifies and smooths incoming mains power to create a stable DC bus that feeds several servo drives in coordinated motion systems. The module’s supervisory circuitry also handles energy recovery during braking events, allowing connected axes to decelerate without external dump resistors while keeping the shared power rail within safe operating limits.

This unit draws three-phase factory power at AC 220 V and accepts an input frequency of 50 to 60 Hz. Line fluctuations are accommodated by an input tolerance of +15/-10%, so operation can continue even when the supply drifts from its nominal value. After rectification, the device provides a nominal DC bus of DC 300 V, which lets downstream inverters maintain accurate current control. For continuous operation, the supply can deliver 25 A to the bus bars, supporting several medium-frame servo drives without derating. These electrical limits are monitored by onboard diagnostics that disconnect the module if demand or temperature exceeds safe thresholds, protecting both the power electronics and the attached motion axes.

The logic section is powered separately at AC 230 V or 400 V, giving manufacturers flexibility when the control cabinet already provides either voltage for PLCs or related equipment. A peak current of 50 A covers short acceleration bursts before the system returns to its continuous rating. Overall bus stability is further maintained by a voltage window of +10/-15% on the downstream supply line, reducing nuisance trips when large loads switch in and out. Thermal management relies on a built-in blower that channels air across the heat sinks, so no additional cabinet fans are required.
