4. Product Introduction (Anti-Template)
The GE DS200DCFBG1BLC is a DC Feedback Power Supply Board (DCFB) used in Mark V-related drive and excitation systems. It supplies control-level DC power (+5 V, ±15 V, and ±24 V) to the drive or exciter and typically provides 115 V AC for enclosure cooling fans.
In addition to the power supplies, the board contains motor or generator field power circuits (excluding the SCR module itself) and driver circuits for the armature SCR gate pulse generators. It also includes monitoring circuits for armature current and voltage, field current, AC line current, and AC line voltage magnitude and phase sequence. The board is cross-compatible with several GE drive families including DC2000, AC2000, CB2000, ME2000, and FC2000. The BLC revision incorporates functional and artwork updates relative to earlier DCFB versions. As a mature Mark V-era board, it is primarily sourced as a spare for existing installations.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full part number (DS200DCFBG1BLC), revision letters, jumper and switch settings if documented, and connector condition. Photograph all labels.
- Functional Testing – Apply appropriate power where possible and verify control supply outputs and basic status indicators. Full system validation requires the host drive or exciter.
- QA & Packaging – Protect edge connectors and components, clean the board, and pack in anti-static protective packaging.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial power supply / control boards. Packaging must protect against electrostatic discharge; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Capacitor Discharge – After removing power, allow adequate time for capacitors to discharge before handling the board.
Jumper and Switch Settings – Record the original jumper and DIP switch configuration before replacement. Incorrect settings can affect power rails or monitoring functions.
Compatibility – Confirm the host system (drive or exciter model) accepts the DCFB revision being installed.
Field Power Circuits – The board interfaces with field and SCR circuits. Incorrect installation or wiring can damage the board or associated power components.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified DS200DCFBG1BLC?
As a legacy Mark V / drive power supply board, availability depends on surplus stock. Typical lead time after verification is 5–20 business days plus standard shipping.
What is the primary function of this board?
It is a DC Feedback Power Supply Board that provides control-level DC supplies, field power circuits, SCR gate drivers, and AC/DC signal monitoring.
What systems is it used with?
GE Mark V-related drives and exciters, including DC2000, AC2000, CB2000, ME2000, and FC2000 platforms.
What control voltages does it supply?
Typically +5 V, ±15 V, and ±24 V DC.
Is the board still in production?
No. It is a mature Mark V-era component. Units are available only through surplus and specialist channels.
What should be confirmed before ordering a replacement?
Exact part number and revision (DS200DCFBG1BLC), original jumper/DIP settings, and compatibility with the specific drive or exciter model.
