GE DS2020FEANRX075A Field Exciter Module

GE DS2020FEANRX075A Field Exciter Module

GE DS2020FEANRX075A Field Exciter Module is a 75 Amp capacity power electronic assembly used in General Electric Mark V Turbine Control Systems and related industrial drive panels.1

⚡ Primary Function: Field Excitation Control

This module’s core purpose is to provide precise regulation of the $\text{DC}$ current supplied to the field winding of a large synchronous generator or motor.

  • Excitation Management: It acts as a controlled 2$\text{DC}$ power source, managing the current that generates the magnetic field in the rotating machinery.3
  • Voltage and Stability: By precisely controlling this excitation current, the module regulates the machine’s output voltage and reactive power (4$\text{VAr}$), which is critical for ensuring grid stability in power generation applications.5
  • Application: It is a key component within the $\text{DS}2020$ family of modular assemblies, widely used in the control systems for gas and steam turbines.
