د.إ8,888.00

The DS2020EXPSG3’s core function is power conversion and regulation specifically for the excitation system of a large generator or motor.

  • Excitation System: It is typically an integral component of the GE EX2000 Brushless Generator Excitation System, which is responsible for controlling the generator’s field current. By controlling this current, the system regulates the generator’s terminal voltage and reactive power output.
  • Power Conversion: The module takes the input power (often 115 VAC and/or 125 VDC) and converts and regulates it to the various low-voltage DC levels required by the control boards, sensors, and components within the EX2000 system.
  • Current Limiting: When the system is powered by a station battery (for backup/ride-through capability), the EXPSG3 often acts as a current limiter to protect the circuit components.

🔎 Technical Details and Series

  • Series: The board belongs to the DS2020 family of modules, which are part of the General Electric Speedtronic Mark V Turbine Control System and related industrial drive platforms.
  • Modular Assembly: The “DS2020” prefix signifies a special assembly style. The EXPSG3 is a physical module composed of several individual printed circuit boards (such as the base power board and a control board, e.g., DS200EXPS) that are stacked and interconnected on a common metal carrier. This modular design enhances component density and system compatibility.
  • Revision: The G3 in the part number indicates it is Group 3 or Revision 3 of the Exciter Power Supply Module within this series, often representing design improvements or updates over earlier versions (like the EXPSG1).

In summary, the DS2020EXPSG3 is the reliable power backbone for the control and protection circuits within the GE generator excitation system, ensuring stable operation for turbines and generators.
