About the DS200DCFBG1BJB

Overview of the DS200DCFBG1BJB Power Supply Board

• The DS200DCFBG1BJB is a power supply board manufactured by General Electric for the Mark V Speedtronic system.
• Its primary function is to supply control level power to drives and the enclosure fan.
• It is used in a range of applications including EX2000, DC2000, FC2000, GF2000, ME2000, CB2000, and AC2000 IGBT drive applications.
• This board belongs to the Mark V Series, which has specific applications in the control and management systems of steam, wind, and gas turbine automated drive assemblies.
• The Mark V Series is one of the final General Electric product series to use their patented Speedtronic control system technology.
• The Mark V Turbine Control System Series, to which this board belongs, is considered a legacy series due to its eventual discontinuation by GE.
• While it's officially a Power Supply Board, the original Power Supply Board for the Mark V Series was the DS200DCFBG1, lacking the DS200DCFBG1BJB's three product revisions.

Hardware Tips and Specifications

• The DS200DCFBG1BJB is a large rectangular circuit board with numerous mounted components.
• Key components include:
  • Seven 4-position DIP switch devices (six of which are grouped on one side for scaling various inputs, e.g., SW4 for VCO output bridge circuit voltage scaling).
  • Twelve configurable jumpers.
  • A single neon lamp indicating a blown fuse in the 115 VAC line.
  • Two LED indicators for blown fuses in the +24 VDC and -24 VDC lines.
• Several notable integrated circuits (ICs) are present on the board, each with factory-printed nomenclatures and specific functions within the board and the broader Mark V Series drive assembly. These ICs include:
  • Voltage and Current Feedback VCO Circuits
  • A Motor Voltage Attenuation Circuit
  • AC Line Magnitude and Zero Crossing Circuits
  • Contactor Drive Circuits
  • Field/Armature SCR Firing Circuits
• These circuits are crucial for functions of the SDCC and LDCC boards within the Mark V Series.
• Other components on the DS200DCFBG1BJB board include:
  • Test points (for checking voltage signals).
  • Various I/O connectors (e.g., 1PL-1 through 1PL-40, 2PL-1 through 2PL-9, 4PL-1 through 4PL-5, and 5PL-1 through 5PL-26).
  • Fuses (for protection).
  • Resistor networks, resistors, capacitors, transistors, heat sinks, transformers, and relays.
• More detailed information on board components and their uses can be found in General Electric's user guides and manuals.
• It's important to note that the DS200DCFBG1BJB's original performance specifications and dimensions have been altered due to its three product revisions.
