Product description

The Siemens 6RA8091-6DS22-0AA0-Z is a SINAMICS DCM (Digital Current Multi-axis) DC converter designed for two-quadrant operation. This unit features a B6C connection and is controlled by a field rectifier (D485/1200 MRE-GEEF6S22). It provides a controllable DC output of 485V and 1200A, suitable for demanding DC motor applications. The input voltage is 400V 3-phase AC.

This SINAMICS DCM converter is engineered for applications requiring precise control of DC motors in both forward and reverse directions, including hoisting, rolling mills, extruders, and large material handling systems. It is ideal for industries such as metallurgy, plastics, and heavy manufacturing.

Stanlo Automation, a veteran-owned supplier of surplus industrial automation equipment, offers the Siemens SINAMICS DCM converter. Ensure your critical applications have reliable power with our high-quality, cost-effective surplus parts.
