The Siemens 6RA7091-6DS22-0 represents a sophisticated solution in DC drive technology as part of the SIMOREG series. Engineered specifically for single-quadrant application, it is compatible with a 400V AC three-phase input. This converter draws a considerable input current of 995A to support a wide range of industrial scenarios.
With an output capability of 485V DC for the armature, the device can deliver a maximum armature output current of 1200A, while maintaining a nominal current of 850A for standard operations. Additionally, it operates a field circuit voltage of 325V DC and can handle 30A in field circuit current.
Employing a sophisticated digital control type that offers closed-loop operation, this unit ensures precision in its responses to load changes. It utilizes thyristor modules for its configuration, optimizing performance. The converter follows a B6C topology, characterized by a six-pulse bridge arrangement, which is effective in single-quadrant applications.
This model is outfitted with a field rectifier type designated as D485/1200 MRE-GEEF6S22, enhancing its capacity to manage complex load scenarios.
Incorporating advanced protection and monitoring features ensures that the field is controlled with digital regulation, providing an extra layer of reliability during operation.
