Description
The GE DS200DCFBG1BKC is a specialized Power Supply and Control Board designed for the General Electric Mark V Speedtronic control system. This board is a critical component in the management of heavy-duty gas and steam turbines, providing regulated DC power and interfacing logic for the drive’s internal circuits. The “DCFB” designation identifies it as a Power Supply Board that integrates various feedback and monitoring functions. This specific revision (G1BKC) features enhanced component stability and is engineered to handle the high-vibration and high-temperature environments typical of industrial turbine enclosures.
Technical Specifications and Datasheet

Product Instructions and Usage
This board should only be handled by technicians familiar with the GE Mark V architecture. Before installation, ensure the system is completely de-energized, as the board handles high-voltage DC inputs. The board features several test points (TP) for checking voltage regulation without removing the module. During replacement, ensure all ribbon cables and high-current wires are securely seated in their respective connectors (typically labeled PL ports). The DS200DCFBG1BKC utilizes EPROM chips that may contain specific site configuration data; verify if these need to be transferred from the old board to the new one to maintain system compatibility.
Common Questions and Answers (Q&A)
What is the main role of the DCFB board? It converts the primary incoming power into multiple regulated DC voltages required by other boards in the Mark V rack while monitoring the health of the power supply.
What does the “BKC” suffix in the part number mean? This indicates the specific hardware revision. “B” refers to the group, while “KC” denotes a specific combination of firmware and component updates implemented by GE during manufacturing.
How do I know if the board has failed? Common indicators include the failure of dependent boards to power up, blown onboard fuses, or “Control Power Fault” alarms on the operator interface (HMI).
Does this board require software configuration? While the board itself is hardware-driven, the system logic it supports is configured via GE’s proprietary software. Ensure that any jumpers on the board match the configuration of the unit being replaced.
Are there user-serviceable parts on the board? Only the fuses and certain socketed EPROMs are typically considered user-serviceable. If a capacitor or integrated circuit fails, the entire board usually requires professional repair or replacement.
