DS3800NSCC

Product Description

The DS3800NSCC from GE is a Speed Current Regulator board for the Mark IV series.  This series was designed for steam or gas turbine management and is built with triple redundant backups on all critical parameters and controls.   

The DS3800NSCC is built with two PCB mating connectors, which are located on opposite sides of the board.  On the right side there is a 218A4637P1 87936-1 connector, and on the left, there is a 218A4553-1A/mp 533002-1.   The board is numbered by tens (from ten to eighty) behind this second connector. It also has one Augat connector.  

The DS3800NSCC has one amber LED, which is labeled “Imok.”  The board has fourteen test points. These are labeled Acom, Fcl, Sra, Tstn, Sp, Tstt, Out, Rcl, Fc1, Tstc, Sus, Rlt, Rla, and Sua.  

The DS3800NSCC is built with polyester film capacitors, including 708D1 m/e .10 +/- 10% 80v. It also has various smaller ceramic capacitors.  The majority of the resistors on the board are made of ceramic covered metal film.

The DS3800NSCC has been marked for alignment along two edges.  It has extractor/inserter clips installed. Extractors help technicians install or extract the PCB from tight locations without damaging circuitry or components, as it gives them both a handle to hold the board by and a lever to action to board out of position with (by pushing the clips against the chassis frame.)

The DS3800NSCC is built with multiple circuits, including quad 2-input exclusive-or gates and quadruple differential comparators.  

All technical support for the DS3800NSCC was originally provided to the end user by General Electric.
