6RA7095-4KS22-0-Z G95+S00+K00+K01+K11 Siemens SIMOREG DC Master Converter, 690 V, 2000 A
Full order code: 6RA7095-4KS22-0-Z G95+S00+K00+K01+K11
The Siemens 6RA7095-4KS22-0-Z is a SIMOREG DC Master converter for single-quadrant DC drives. It has a 690 V three-phase input and a rated DC output of 830 V / 2000 A, plus an integrated controllable field rectifier. This configuration comes factory-fitted with the options G95, S00, K00, K01 and K11, which add PROFIBUS communication, technology software, terminal expansion and the mounting hardware for option boards. SIMOREG DC Master converters power large DC motors in rolling mills, extruders, winders, cranes and test benches, and many of these installations are still in operation. Siemens has discontinued the 6RA70 series, so this unit is mainly sourced for like-for-like replacement.

Product Lifecycle and Successor
The SIMOREG DC Master 6RA7095-4KS22-0 is discontinued (since 19 November 2020, according to the data below). The listed successor platform is SINAMICS DCM, with the 6RA8095-4KS22-0AA0 as the recommended replacement. A like-for-like 6RA70 avoids re-engineering, rewiring and recommissioning, while a migration to SINAMICS DCM is the long-term route. Atlantech Drives can quote both options.
Why Replace Like-for-Like
- Minimal downtime: direct exchange of a failed converter, with the same mounting, power connections and options
- Existing parameters and communication carry over unchanged (PROFIBUS via G95)
- No re-engineering of the control cabinet or automation program
- Proven technology: robust 1Q DC drive for high-power DC motors
