About the DS200DCFBG1BLC
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.
