Siemens C98043-A7117-L1 6RY1803-0CM01 – DC Drive Power Supply Module | SIMOREG DC Master Platform
Engineering Background
The Siemens SIMOREG DC Master series represents the industry benchmark for fully digital, closed-loop DC drive control systems. Designed for demanding industrial environments, these drives deliver precise speed and torque regulation across a wide range of motor ratings. The C98043-A7117-L1 (order number 6RY1803-0CM01) is the dedicated power supply board that conditions and distributes regulated DC voltages to the drive’s control electronics, gate firing circuits, and field supply subsystems.
Product Positioning
This module is a critical spare and replacement component for plant engineers and maintenance teams operating SIMOREG DC Master 6RA70 series converters. Its failure directly impacts drive availability; stocking a verified replacement eliminates unplanned downtime and protects production continuity. Konmask.com supplies this part with full traceability and pre-shipment functional verification.

- Traceable Sourcing: Every unit at Konmask.com is sourced through verified supply channels with documentation available on request.
System Architecture & Signal Flow
Within the SIMOREG DC Master architecture, the C98043-A7117-L1 receives primary AC input from the drive’s internal transformer secondary and generates multiple regulated DC rails. These rails power the CUD (Central Unit Drive) control board, the pulse transformer firing circuits for the thyristor bridge, the field supply regulator, and the operator panel interface. A fault on this module manifests as a complete drive shutdown (F001/F002 class faults) or erratic firing behavior, making it a primary diagnostic target during drive commissioning and fault analysis.
Sourcing & Quality Verification
- All units undergo incoming inspection including visual examination, PCB integrity check, and where applicable, powered bench test against reference voltage specifications.

Technical FAQ
Q: Is C98043-A7117-L1 the same as 6RY1803-0CM01?
A: Yes. C98043-A7117-L1 is Siemens’ internal PCB part number; 6RY1803-0CM01 is the orderable spare part number. Both refer to the identical module.
Q: Which SIMOREG drives use this module?
A: This PSU board is used across the SIMOREG DC Master 6RA70 series. Confirm compatibility by checking the drive’s spare parts list (available in the 6RA70 operating instructions, Appendix).
Q: Can I test this board before installation?
A: Yes. Bench testing with a variable AC source and a multimeter against the documented output voltage rails is recommended before installation in a live drive.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Out-of-stock lead time is 2–6 weeks depending on sourcing. Contact us for real-time availability.
Q: Do you provide installation support?
A: Yes. Our engineering team can provide guidance on safe board replacement procedures and post-installation commissioning checks.
