The DS3800DVRC1A is a regulator-style circuit board for turbines. The DS3800DVRC1Ais featured in the Mark IV Speedtronic line up from General Electric (GE). A regulator circuit boards purpose is to prevent energy spikes by keeping a steady current or energy flow through the turbine. The DS3800DVRC1A has three Potentiometers or they are sometimes referred to as variable resistors. Each variable resistor has an easy to grab black knob. Each knob is clearly marked with the numbers zero to one-hundred. There are ten-degree increases between zero to one hundred to easily get the current flow you require with a simple turn. There are also little arrows on the knobs for easy identification. Once the current flow is adjusted the board relies on the five EEPROM devices on the board. These EEPROM old the programs for the board to function. These devices, however, cannot be reprogrammed. If more programming is required there is a section labeled "SPARE" on the board where an addition EEPROM may be installed. This section already has current point around it so an EEPROM can easily be installed.
The parts of the board that make it a regulator are called resistors. There are two types of resistors on this board. The first type of resistor is small but numerous in number. There are around seventy-six or so on this particular board. These smaller resistors are banded with a few different colors. These colors correspond with a code to left the operator know how many ohms each resistor can withstand.
The second type of resistors is called "power resistors". These power resistors vary in size from small to large and handle high power energy that may flow through the board during an energy spike.
