The DS3820EPSA is a smaller circuit board featured in General Electric’s Speedtronic Mark IV Turbine series. The gas and steam turbines are a fast way to provide energy and flexible fuel. A gas turbine builds pressure by using a combination of air and fuel in an internal combustion engine to create a mixture of gases to turn the turbine blades. A steam turbine uses a large boiler which is filled with water. The boiler is then heated to create large amounts of steam which then turns the turbine's blades. The energy produced by the spinning turbine blades is then harnessed for other purposes. The DS3820EPSA has six grey diodes, six bright red diodes, and eight black and silver diodes. These types of diodes only allow energy to move in one direction through them. The DS3820EPSA also has another type of diode called a light emitting diode or LED. The DS3820EPSA has three amber colored LEDs. A light emitting diode will light up as an energy current passes through them. The DS3820EPSA has four small yellow capacitors and three medium yellow capacitors. Capacitors are used to create an electrical field to store extra energy in for later use. The DS3820EPSA has three large glass fuses. The DS3820EPSA has two large grey rectangular resistors with the power resistance ability marked on the face. The DS3820EPSA has three small traditional resistors that use a color code to decipher the power resistance. The DS3820EPSA has two red female terminals with two ports, there is also a larger female terminal with five ports. The DS3820EPSA has a very large black box on one edge of the circuit board. The DS3820EPSA is easy to install with four slide in screw ports.
