Description

The DS3800NPSZ1B1A was made as part of the Speedtronic Mark IV (MKIV) by GE (General Electric). The Mark systems are counted on for operating and automating the functions of both steam and gas turbine. The turbine’s systems are also protected from dangerous conditions by the Mark IV. Since the late 1940s, the Mark systems have been relied on for efficient operation.

Mark IV is the third system made for the Mark series to control turbines. The first of these series was introduced in the 1960s (1968) and was called Mark I. All aspects of operation in steam or gas turbines are managed by the Mark IV system. Mark IV controls shutdown and startup, monitors the injection levels of fuel, and monitors the turbine’s temperature level. A diagnostic system is featured in the Mark IV which allows users to determine what is wrong in the case of a problem. Visual records of trips are printed by a printer that is built into the system. The DS3800NPSZ1B1A is what is called a power supply printed circuit board. Power supply circuit boards typically featurea number of diodes which are lined up in rows. An LED, or light-emitting diode, is often seen on the power supply board. This LED is lit up when the device is functioning. A variety of capacitors can often be found on the surface of power supply boards like the DS3800NPSZ1B1A. Series of transistors are typically found on boards like the DS3800NPSZ1B1A. Possibly located on the surface of the DS3800NPSZ1B1A is a series of small resistors.
