DS3800NEPA1C1A

Product Description

GE created the DS3800NEPA1C1A as a motor exciter power supply for the Mark IV Speedtronic series. The Mark IV, which was created for gas and steam turbine control management, is created upon machine-verifiable redundancies and integrated chipsets. These intentional redundancies help keep the entire system working in the event of an electronics failure in one module, thus minimizing downtime.

The DS3800NEPA1C1A is a vertically bulky printed circuit board. This is due to the two Raycom Electronics 44B379508-G02 modules attached to the board. Other specs include:

• -two straight-pin (male) connectors on the left side of the board. The first of these, a 6-pin connector, has a 2-2-2 pattern. The second, a 7-pin, has a 2-1-1-3 pattern.

• -four circuits connected to the board.

• -one jumper. This can be set to "nr" or to "rev."

• -four potentiometers (rotary.)

• -nine each large resistors and large capacitors. The large resistors have orange, white and gold bands. The capacitors are orange. The board has other, smaller capacitors and resistors.

• -one terminal connector (male) located in the upper left of the board.

• -alignment marked on two edges (A through L and 10 through 80.)

• -factory drilled, twice each corner, along the edge of the board, and four times offset from the center.

• -one thermistor (red,) or thermal resistor. Since thermal resistors lose resistance as they heat, they can assist with voltage regulation and circuit protection.

Manuals and data sheets for the DS3800NEPA1C1A were originally provided by GE. Installation instructions and maintenance schedules may be found within these publications, and are an excellent resource for technical support.
