Product Number: DS3800NPSE1D1F
Manufacturer: General Electric
Series: MKIV
Description: Input/output circuit board
The DS3800NPSE1D1F is part of the GE Speedtronic MKIV gas turbine controller.

The DS3800NPSE1D1F is a power supply board. The product is part of the Speedtronic Mark IV series for turbine control and automation. The printed circuit board is manufactured by GE or General Electric.

The DS3800NPSE1D1F has many medium-sized yellow capacitors. There are thirty-seven (37) of these capacitors in total. Twenty-seven (27) of these capacitors are arranged vertically in the lower half of the DS3800NPSE1D1F. Directly above these capacitors are another nine (9) capacitors arranged horizontally. The last capacitor is located near the top right corner of the DS3800NPSE1D1F. The DS3800NPSE1D1F has two (2) black connector ports on the left side. These ports are male connector ports and are located vertically on the board surface. These ports are labeled JH and JA. The third black connector port is smaller in size and is located on top of the DS3800NPSE1D1F. The port name is JC. Six (6) fuses can be seen in the left half of the DS3800NPSE1D1F. The left half of the board also has one (1) MOV or metal oxide varistor. This varistor is a round red color. Along the top of the DS3800NPSE1D1F are three (3) blue variable resistors, also known as potentiometers. The resistance of each potentiometer can be adjusted using a dial on the top of each device. One (1) orange LED or light-emitting diode is placed on the right side of the DS3800NPSE1D1F. Two small black transistors are located near this LED.
