PRODUCT INFORMATION
Product Overview
The General Electric DS3800NPSE1E1G is a power supply circuit board built for the Speedtronic Mark IV control platform. The Speedtronic Mark IV series delivers automated turbine regulation and control functions. It also provides dedicated protection against unsafe operating conditions. This board integrates discrete circuit components to support standard operations within the turbine control framework.
Hardware on the DS3800NPSE1E1G board includes three light blue male connector ports. Two ports are larger and vertically aligned, while the third port is smaller. The assembly includes twenty-seven vertical blue capacitors labeled C1 through C27. Nine silver capacitors named C31 through C39 align in a horizontal row. Four onboard fuses are present, alongside spaces for two additional fuses.
