The DS3800DVRC1A1 circuit board is part of General Electric (GE) Mark IV Speedtronic Turbine line up. The DS3800DVRC1A1 works as a current regulator. A regulator keeps the energy flow constantly throughout the machine despite possible energy spikes.
The DS3800DVRC1A1 is a very intricately designed board with various parts. The most vital components on this board are the metal power resistors that disperse high power energy. There are twelve power resistors all varying sizes. The DS3800DVRC1A1 also has around seventy-five small resistors. They are a reddish color and each one has a color band like marking. Each band on the resistors is a color based code to calculate the number of ohms that can be passed through each resistor. The DS3800DVRC1A1 is considered a "daughter" board which means it attached to a larger circuit board to function properly. In order for easy installation, the DS3800DVRC1A1 has anchors in each corner, and a wiring harness to allow for communication between boards. The programming of the board is stored in five EEPROMs. These EEPROMs hold all the functional programming the board will need. These units are not capable of being re-programmed. There is a small section on the board where another EEPROM can be installed if needed. This spot on the board is clearly labeled "SPARE" and has the appropriate connection points around it.
The DS3800DVRC1A1 also allows the worker to control how much energy or current flows across the board at one time. In order for this to be accomplished the DS3800DVRC1A1 has three knobs on its face. These knobs are known as variable resistors or sometimes call Potentiometers. These variable resistors each have a range printed on the knobs of zero to one-hundred, (with ten-degree increases in between). The knobs also have a tiny white arrow on top of each one. In order to adjust the current or energy flow, all the worker needs to do is turn each knob to the degree they need it.
