د.إ8,888.00

The main role of the DS2020EXPSG1 is to act as a microprocessor-controlled power converter that provides a stable and regulated power source for the generator’s excitation system.

  • Excitation System Support: The excitation system is vital for maintaining the generator’s terminal voltage and reactive power. The EXPSG1 supplies the low-voltage DC power needed by the control logic boards and other components that regulate the high-power exciter field current.
  • Voltage Regulation: The module handles the conversion and regulation of input power to the specific DC voltages required by the different logic and control boards within the excitation system. This ensures stability and reliability in the overall power generation process.
  • Modular Assembly: The DS2020EXPSG1 is a special assembly module, often built from two separate circuit boards (such as the DS200GDPA and the DS200EXPS board itself), mounted on a metal carrier with heat sinks, transformers, and protection components.

الوصف

The GE DS2020EXPSG1 Exciter Power Supply Module is a critical component used in the General Electric Speedtronic Mark V Turbine Control System and its associated excitation drives, such as the EX2000 brushless generator excitation system.

It is a specialized modular assembly designed to provide, convert, and regulate the necessary power for the excitation control circuitry.

💡 Primary Function: Exciter Power Supply

The main role of the DS2020EXPSG1 is to act as a microprocessor-controlled power converter that provides a stable and regulated power source for the generator’s excitation system.

  • Excitation System Support: The excitation system is vital for maintaining the generator’s terminal voltage and reactive power. The EXPSG1 supplies the low-voltage DC power needed by the control logic boards and other components that regulate the high-power exciter field current.

⚙️ System and Series Context

  • Series: The module belongs to the GE DS2020 family of printed circuit boards, which are integral to the Mark V Speedtronic legacy series of control systems used for gas, steam, and wind turbines.
  • Acronym Breakdown:
    • DS2020: Indicates a special assembly board within the Mark V system.
    • EXPS: Stands for EXciter Power Supply.
    • G1: Denotes its Group 1 classification and original, unrevised functional version within that group.

Since GE no longer manufactures these Mark V components, the DS2020EXPSG1 is considered a legacy part, typically available only as used, reconditioned, or repaired units today.
