Functional Description

DS200GASQF1AFB is a General Electric Software EPROM Component designed and developed by GE. It is a part of the Mark V control system. Mark V stands as a series of microprocessor-based turbine control systems, meticulously crafted for the purpose of turbine management. The versatility of the Mark V is notable, as it is suitable for deployment on medium or large steam turbines, heavy-duty gas turbines (whether single or two-shaft configurations), and even gas turbines derived from aircraft technology.

Mark V Panel Features

• The panel construction for the Mark V is designed to meet NEMA type 1 specifications, ensuring its reliability and safety in various environments. Natural convection cooling is employed to regulate the temperature inside the panel, achieved by circulating air through strategically placed lower and upper vents, which are thoughtfully located in the forward-facing doors of the panel. The panel material is primarily composed of hot-rolled, low carbon, 12-gauge steel, measuring .105 inches in thickness. There's one exception to this, where access plates utilize thicker gauge steel at .187 inches, ensuring durability and protection.
• In the painting process of the Mark V panel, environmental considerations are taken into account to adhere to current Environmental Protection Agency (EPA) requirements. The Mark V paint process leverages a powder coating technique, which involves a multi-stage pretreatment section, an environmentally controlled structure for the coating booths, and a curing oven. The pretreatment section serves to clean the surfaces, remove oxide scale, provide corrosion protection, and enhance the uniform adhesion of the powder coat. The parts, after being pretreated, are electrically grounded and then passed through a cloud of negatively charged powder, ensuring complete and even coverage. Subsequently, the parts enter an oven where the powder is "flowed" and the finish is cured.
• Three significant advantages of this Powder Coating process are as follows:
  • It boasts a notably high transfer efficiency rate of 98%, in stark contrast to the more typical 40-60% efficiency obtained when using liquid spray methods.
  • The use of powder coating significantly reduces emissions of Volatile Organic Compounds (VOCs), contributing to environmental sustainability.
  • The powder coating process enhances the overall quality and appearance of the Mark V panel, resulting in a professional and polished finish.
• The Mark V panel comes in three fundamental physical configurations, which are Simplex, TMR (Triple Modular Redundancy), and Large Steam TMR.
