DS200DSFBG1A

Product Description

The DS200DSFBG1A functions within General Electric Mark V systems, exciters, and drives as a Driver Shunt Feedback Board. The DS200DSFBG1A board was designed and marketed by GE along with other Mark V components until the early 2010s when the system entered a post-production phase. While Mark V components may not be available from the OEM any longer, they are still available here from AX Control.

The DS200DSFBG1A is a square-shaped board, which, typically to any Mark V Series circuit board product, stores all of its hardware components by attaching them to its base circuit board.  As a driver shunt card, the DS200DSFBG1A board can generate faults via the current feedback that it is designed to monitor. Two such faults are an IOC or Internal Overcurrent fault when current exceeds 250% of the rated current, and a DI/DT fault, which occurs when a step change of 100% or greater occurs in the rated shunt current. These are not the only functional fault applicable to this Mark V turbine control system series product, especially given the singular A-rated functional revision that may make great changes to the normative functionality of this General Electric product.

The DS200DSFBG1A is built with a transformer near one edge. The board also has multiple transistors, vertical pin connectors, and stab-on connectors, as well as more than a dozen eyelets on the board that are ringed with a conductive material. These ringlets are used to connect device gates and emitters. Additional components of use on the base board of this DS200DSFBG1A model include integrated circuits, LED indicators, resistor network arrays, and varistors, as well as resistors and capacitors. The DS200DSFBG1Aboard is marked on two edges where stiffeners should be installed. Corners are drilled for mounting and installations purposes, with two edges being additionally marked to help with alignment during this process. While not a whole lot of original, factory-printed instructional manuals seem to be available online detailing this DS200DSFBG1A Driver/Shunt Feedback Board, its functional DS200DSFBG1A product number alone is source of a plethora of valuable information, including its Mark V Series assembly, its DSFB functional abbreviation, its normal style of printed circuit board coating, its group one Mark V Series grouping, and its singular, A-rated functional revision.
