GE DS200DCFBG1BLC Power Supply Board Mark V Ge Turbine Control

Product Details:

The GE DS200DCFBG1BLC is a DC Power Supply Feedback Board part of GE’s Mark V series, designed as a revised replacement for the original DS200DCFBG1. It offers broad compatibility with GE exciters and driver and Mark V Turbine Control Systems used for wind/steam/gas turbines.

Its core role is power management: it accepts 38–115 VAC input from the Control Power Transformer, delivers control-level power to drives, and supplies 115 VAC to enclosure fans. It integrates critical circuits and features five test points for voltage monitoring. Safety and diagnostics are ensured via three protective fuses, two LEDs, a neon lamp, 12 configurable jumpers, and seven DIP switches. It requires static-sensitive handling, as lethal voltages may persist post-power-off, and installation follows GE’s manual guidelines.

Key Features:
Wide Compatibility: Works with multiple GE exciter/drive series and Mark V turbine systems, making it a versatile replacement for legacy setups.

Multifunctional Power Delivery: Provides regulated control voltages and 115 VAC for fans, supporting both drive operations and thermal management.

Integrated Control Circuits: Includes VCOs, motor field power circuits, and SCR driver circuits, enabling precise drive/turbine regulation.

Diagnostic & Safety Tools: Fuses, test points, LEDs, and a neon lamp facilitate voltage monitoring and fault detection; jumpers/DIP switches allow customization for external needs.

Voltage Persistence Warning: Lethal surface voltages may remain after power-off, requiring careful handling—critical for operator safety during maintenance.

Mark V Turbine Alignment: Tailored to Mark V’s wind/steam/gas turbine control needs, ensuring seamless integration with the system’s Speedtronic technology-driven architecture.
