Product Introduction
GE DS200DCFBG1BLC is a DC Feedback (DCFB) power supply board for the GE Speedtronic Mark V control system family. The board supplies system control-level power to Mark V drives and also provides power for chassis cooling fans.
The “DCFB” designation refers to its DC feedback function. The board includes circuitry for monitoring AC and DC signals such as armature current and voltage, field current, and AC line current and voltage. This feedback supports accurate regulation and protection within GE Mark V drive assemblies.
The board accepts an AC input rated from 38 to 115 VAC, with a frequency range of 0 to 500 kHz depending on input voltage. It includes AC/DC monitoring circuits, control-level power circuits, motor field power circuits, and driver circuits. Configuration is performed through 12 user-configurable jumpers and 7 DIP switches. Board status is indicated through 2 LEDs and 1 neon lamp, and voltage levels can be checked at 5 integrated test points.
The DS200DCFBG1BLC is compatible with multiple GE Mark V drive families, including DC2000, AC2000, CB2000, ME2000, and FC2000. As a legacy Mark V product, the exact jumper map, DIP switch settings, and output configuration should be verified from the physical board label and the applicable GE Mark V manual before installation.

Note: Public documentation confirms the DCFB function, input range, indicators, jumpers, and DIP switches, but the exact output rails, jumper map, DIP switch table, and compatible drive revision for DS200DCFBG1BLC should be confirmed from the physical board label and GE Mark V system documentation.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the PCB surface, connectors, DIP switches, jumpers, fuses, LEDs, neon indicator, and mounting hardware for damage or corrosion.
- Continuity and insulation check. AC input terminals, DC output paths, fuse circuits, and test points are verified for correct continuity and no short circuits.
- Configuration verification. The 12 jumpers and 7 DIP switches are recorded and compared against the original board or system documentation.
- Indicator and fuse check. The 2 LEDs, neon lamp, and 3 fuses are inspected for proper presence and condition.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Verify jumper and DIP switch settings. The DS200DCFBG1BLC has 12 jumpers and 7 DIP switches; incorrect settings can cause improper output or drive faults.
❗ Confirm the exact output configuration. Control-level DC rails and fan power outputs must match the installed drive or chassis requirement.
❗ Check AC input rating before power-up. The board accepts 38–115 VAC; applying the wrong input voltage can damage the board or downstream equipment.
❗ Do not substitute with non-DCFB boards. DS200DCFBG1BLC is a DCFB power/feedback board and is not interchangeable with I/O, processor, or communication boards.
❗ Match the target drive family. Compatibility depends on whether the installed system is DC2000, AC2000, CB2000, ME2000, FC2000, or another Mark V drive.
❗ Use the 5 test points for verification. Voltage levels should be checked at the integrated test points before returning the system to service.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
