About the DS200EXPSG1ABB
The DS200EXPSG1ABB is a power supply board used within GE’s Mark V turbine control system. The DS200EXPSG1ABB is a Mark V Speedtronic series system, specifically designed to manage and control industrial turbine systems. The DS200EXPSG1ABB power supply board is used to provide signals for inputs to measure both AC and DC input power. The DS200EXPSG1ABB board also offers current limiting action for times the board is energized by its correspondent station battery. Please remember that while the information provided below is accurately sourced from the correct GE manuals, this particular PCB component has been revised three times and may feature slightly different dimensions.
Hardware Tips and Specifications
The DS200EXPSG1ABB model has a number of unique components including:
- inductor coils
- terminal blocks
- pin connectors
- a transformer
- several rectifiers
- factory-drilled holes for mounting purposes
One of this DS200EXPSG1ABB board's main features is a singular jumper, designated as manually moveable hardware, and embellished with the simple label JP1. The JP1 connector will connect to the center tap of the T1 secondary connector to the ground. For more information on this drive refer to the GEI-100168 Configurable Hardware for Bulk Power Supply Board Instruction Manual. While this is a movable style of jumper present on the face of the EXPS PCB, it remains important to be certain your jumper setting matches that of the board you are replacing. Beyond jumper compatibility, prospective buyers of the DS200EXPSG1ABB board component part may want to consider the PCB coating present on this relatively outdated Mark V legacy model. This particular DS200 product is protected with a normal-style printed circuit board coating, which, while certainly thicker than the special conformal coating seen in many similar General Electric circuit boards, offers nothing near the same exhaustive layered coverage unique to conformal coating. The normal PCB coating specific to this product is made evident in the "G1" group designation in DS200EXPSG1ABB's product number.
Installation Tips and Specifications
As with many from the Mark V legacy series of component printed circuit boards, the DS200EXPSG1ABB model is normally-coated, therefore requiring an increased level of precautionary measures for voltage and static-safe PCB handling. When replacing the board and assessing if there is damage, make sure that every piece of equipment the DS200EXPSG1ABB board is being used with is turned off. All of the bulk power supply elements must be removed when replacing this board; please ensure there is zero potential at all of the power supply assembly connections. When removing the power supply assembly, carefully disconnect all of the attached connectors, then loosen the four mounting screws, carefully lifting the power supply out of the cabinet. This should ideally all be performed with static-proofed clothing and gloves. Once all of the connections have been removed and the DCPL, 3GDPL, and 4GDPL have been unplugged from the old EXPS board, insert the new DS200EXPSG1ABB board into the cabinet. The final step in this process is to reconnect the detached connector, in order to carefully reinstall the power supply to the cabinet.
