About the DS200DCFBG1BJB
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. 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.
