The DS200DCFBG1BGB circuit board is a power supply board specially designed for the Mark V series turbine control system, playing a key role in the field of industrial automation. Manufactured by General Electric (GE), a brand with deep technical accumulation and wide market recognition in the field of electrical equipment manufacturing, this circuit board belongs to the Mark V series. The Mark V series is commonly used in the control and management systems of automatic drive components for steam, wind, and gas turbines, and adopts the patented Speedtronic control system technology.
Function & Application
Primary Role: Supplies control-level power to drives and chassis fans. Critical for drives in AC2000, CB2000, DC2000, FC2000, ME2000, EX2000 series machines, ensuring stable power distribution and continuous operation of all components.
Hardware Specifications
Physical Design: Large rectangular board with extensive component integration, including 7 4-position DIP switches and 12 configurable jumpers. Six DIP switches are grouped on one side for scaling or modifying inputs (e.g., SW4 adjusts voltage applied to VCO output bridge circuits).
Circuit Composition: Comprises motor excitation power supply, drive circuits, AC/DC monitoring, and control-level power modules. Integrates voltage/current feedback VCO circuits and motor voltage attenuation circuits for stable power delivery and signal processing.
Indicator Lights: Features one neon lamp for 115VAC fuse status, and two LED indicators for +24VDC and -24VDC fuse conditions, enabling quick fault detection.
Technical Parameters
Rated Voltage: Operates within 38–115VAC, directly powered by a control power transformer.
PCB Coating: Equipped with a standard coating to protect against environmental factors and extend service life.
Revision Versions: Available in 3 revisions, with the first two versions featuring backward compatibility.
Application Areas
Widely applied in petroleum, natural gas, power generation, etc.
