6RA7093-4DS22-0

The Siemens 6RA7093-4DS22-0, part of the SIMOREG series, is specifically crafted as a DC master rectifier suited for high-power industrial settings. This rectifier operates on a three-phase input voltage of 400 V AC and draws a considerable input current of 1326 A. When converting power, the unit provides an output voltage of 485 V DC along with a substantial output current capacity of 1600 A. For continuous operations, the rated output current remains at 1190 A, ensuring reliable performance in demanding applications.

In addition to its main functions, the rectifier includes a field input at the same voltage level of 400 V AC and offers a field output voltage of 325 V DC. The field output can handle up to 40 A of current. To manage thermal conditions effectively, the system features a separate cooling method, maintaining optimal performance within its designed ambient temperature range. Depending on various factors, the rectifier supports temperature conditions of up to +35°C or +40°C.

The thyristor setup consists of disk thyristors integrated with a fuse assembly for enhanced safety and reliability. The converter employs a B6C connection type, suitable for single-quadrant operations. Control is facilitated through single-quadrant digital methods, while the field control operates in an uncontrolled manner, allowing for straightforward configurations and operations.
