Product Description:

The TVM 2.2-050-220/300-W1/220/380 is a power supply module produced by Bosch Rexroth Indramat for the TVM Power Supply Modules series. In an automation cabinet, it converts incoming three-phase mains power into a stable DC bus that feeds multiple drive controllers, allowing coordinated motion of servo axes without separate rectifiers. The module also furnishes auxiliary voltages for control electronics so the associated drives and logic circuits share a common energy source, simplifying wiring in industrial automation lines. This arrangement supports centralized power distribution in multi-axis systems and keeps the cabinet layout more orderly.

This unit can deliver a continuous output of 25 A, giving drives enough current for steady torque production under rated load. It accepts an input of AC 220 V from the facility mains, and the permitted supply frequency spans 50/60 Hz, so the same hardware can operate with either common grid standard. Line variations are handled by a tolerance window of +15/-10%, and within that range the internal regulation maintains proper charging of the DC link. Downstream in the cabinet, the bus voltage is held at DC 300 V, which matches the needs of compatible Indramat servo inverters and supports stable power transfer between the supply and the connected drives.

The control section draws its own supply from either AC 230 V or 400 V, letting the cabinet builder use the available auxiliary source. For short duty peaks, the module supports a type current of 50 A, allowing brief acceleration surges without tripping the protective circuitry. Thermal management is provided by a built-in blower that forces air across the heat sink, so no external fan kit is required. The device is engineered in configuration 2, which uses the connector layout and internal protection arrangement intended for this model.
