GE DS3800NPPB POWER SUPPLY CIRCUIT BOARD

GE DS3800NPPB POWER SUPPLY CIRCUIT BOARD

Part Number DS3800NPPB Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS3800NPPB is a Power supply Circuit Board developed by GE for the Mark IV gas turbine control system. The Mark IV is a series in the Mark series that is used to automate gas and steam turbines and protect them from damage. The circuit is possess three large inductors or coils. 

Two inductors are paired together and wired together on the boards lower half. The other two inductors can be found on either end of the GE boards top half. Three capacitors are arranged in a vertical row near the bottom of the board. On the opposite side of the circuit board, there are two brown capacitors. This GE board has one large metal diode near the lower-left corner. It has five medium-sized yellow capacitors. Five of these capacitors are located in the upper left corner. The remaining two of these capacitors are located in the upper right corner. The circuit board has one long grey resistor near the center of the top. The resistor is identified by the part number IRC 8845. It is connected to three-terminal blocks. The color of these terminal blocks is red. Two of the blocks have twelve terminals each, while the other has five terminals. The board is surrounded by a slew of very small diodes and capacitors.
