About the DS200DCFBG1BLC

Overview of the General Electric DS200DCFBG1BLC Power Supply Board

• The DS200DCFBG1BLC is a power supply board designed by General Electric for their Mark V series of optional and replacement boards.
• This board is cross-compatible with various GE exciters and drives, including the DC2000, AC2000, CB2000, ME2000, and FC2000 series.
• It provides system control level power to the installed drive and supplies electricity to the enclosure fan.
• The board accepts sourced AC inputs ranging from 38 to 115 VAC, with accompanying frequencies from 0 to 500 kHz depending on the input voltage.
• While it functions as a power supply board, the original Mark V Turbine Control System Series power supply board was the DS200DCFBG1, which lacks the three significant functional revisions present in the DS200DCFBG1BLC.
• The broader Mark V Turbine Control System Series has specific applications in the management and control systems of wind, steam, and gas turbine automated drive assemblies.

Hardware Tips and Specifications

• The DS200DCFBG1BLC features intricate circuit systems designed to power most of the drive. These include:
  • An AC and DC monitoring circuit
  • A control level supply circuit
  • A motor field power circuit
  • A driver circuit
• Users can configure twelve jumpers and seven DIP switches on the board to meet specific external requirements.
• Onboard indicators (two LEDs and one neon lamp) communicate board status and provide diagnostic information.
• Three integrated protective fuses safeguard against significant interruptions or surges to the currents on the DS200DCFBG1BLC board and its associated Mark V Series automated drive assembly.
• The board includes five test points for periodic voltage level monitoring. These test points are:
  • P5 +5 V dc Power Supply Testpoint
  • DCOM 0 V Test Signals Common Reference Point
  • P15 +15 V dc Power Supply Testpoint
  • N15 -15 V dc Power Supply Testpoint
  • ACCT DCFB to SDCC ACCT Signal Testpoint
• The names of these test points reflect their factory-printed labels, voltage ratings, and functionality within the board and the Mark V Turbine Control System Series.
• The DCFB and SDCC boards, which are accessed by the ACCT testpoint, are also available for purchase and repair in various revision styles.

Installation and Safety

• It is imperative to follow the provided installation parameters for both the DS200DCFBG1BLC and the drive to ensure proper operation.
• The DS200DCFBG1BLC printed circuit board should be handled as a static-sensitive product.
• Be aware that potentially lethal surface voltages may exist on the board during or after normal functional use, even after the power is off.
• For detailed wiring and installation guidance, refer to the series manual and the device datasheet.
• General Electric originally provided technical support for all boards in the Mark V series.
