About the DS200DCFBG1BNC
The DS200DCFBG1BNC is a power supply board specifically manufactured for General Electric's Mark V series of replacement and optional boards. It is an integral component of the Speedtronic Mark V control system, which finds applications in the control and management of wind, steam, and gas turbine automated drive assemblies. This card provides system control level power and supplies electricity to the enclosure fan. It is compatible with various GE brand exciters and drives, including the FC2000, AC2000, DC2000, ME2000, and CB2000 series.
The Mark V Series remains highly esteemed as it is one of the final GE Mark product series to widely incorporate the patented Speedtronic control system technology. The DS200DCFBG1BNC is not the original power supply board for the Mark V Series; that would be the DS200DCFBG1 parent Power Supply Board, which lacks the DS200DCFBG1BNC's three significant product revisions.
Hardware Tips and Specifications
The DS200DCFBG1BNC features unique hardware components and specifications. It safely accepts input voltages ranging from 38 to 115 VAC.
The board includes five circuits:
- a driver circuit
- the control level supply circuit
- a motor field power circuit
- an AC monitoring circuit
- a DC monitoring circuit
Three protected fuses are onboard to prevent circuit disruptions from interruptions or surges.
Integrated LED and neon indicators alert users if any fuses require attention.
Five test points are available for monitoring voltage levels. These include:
- P5 Regulated Power Supply Test Point
- DCOM Test Signals Common Reference Test Point
- P15 Positive Power Supply Test Point
- N15 Negative Power Supply Test Point
- ACCT ACCT Signal DCFB/SDCC Test Point
The naming of these test points combines their factory-printed labels, voltage ratings, and functionality within the board and the Mark V Series assembly. Users can customize the board's functionality using twelve configurable jumpers and seven DIP switches. The DS200DCFBG1BNC incorporates a voltage protection and suppression strategy featuring various capacitors, transistors, resistors, diodes, and integrated circuits. While normally having twelve configurable jumpers, this board utilizes thirteen, due to its elevated revision history which includes the JP13 Scaling Select for Shunt Jumper. Jumpers labeled JP13 or JP14, if present, are considered harmless, vestigial structures as they are described as deleted jumper styles in the original manual.
Installation and Support
Installation parameters provided with the board and drive must be followed to ensure proper operation. An illustrated guide to wiring and installing the board is available in the device’s manual and datasheet. The DS200DCFBG1BNC should be handled as a static-sensitive product and may have potentially lethal surface voltages during or after use. General Electric originally provided technical support for all Mark V series boards.
