Functional Description

DS2020FEANRX050A is a Field Exciter Module developed by GE. It is a part of the Mark V control system. The exciter module operates at 600 volts and 50/60 Hz, is designed for single-phase use. It features a DC output of 500 volts at 50 amps and weighs approximately 56 lbs. Its construction is housed in a robust, long rectangular metallic chassis, designed for durability and protection of internal circuitry.


  • Access to Internal Circuitry: It features two open sides that allow easy access to the internal circuitry. This design facilitates maintenance tasks such as inspection, troubleshooting, and component replacement without requiring extensive disassembly.
  • Mounting Capability: On the back of the chassis, there are factory-drilled mounting holes positioned at each corner. These holes are strategically placed to ensure secure installation in various mounting configurations, enhancing stability and reliability in industrial environments.
  • Structural Integrity: The closed sides of the chassis also incorporate factory-drilled holes. These holes not only contribute to the structural integrity of the unit but also assist in heat dissipation and airflow management, crucial for maintaining optimal operating conditions.
  • Transformers: Positioned prominently on the circuit board are four white transformers. These transformers play a vital role in stepping voltage levels up or down as required, ensuring proper signal processing and distribution throughout the power supply unit.
  • Connector Configuration: Adjacent to the transformers is a 10-pin male connector located on the top left side of the board. This connector serves as a central point for interfacing with external systems, facilitating signal input and output for seamless integration into larger control and monitoring systems.
  • Cable Connections: At the bottom of the unit, there are two large cables securely fastened to connectors. These connectors are meticulously designed to provide a reliable interface for power transmission and control signals.
  • Secure Affixation: The cables are affixed using nuts, ensuring a secure and stable connection that minimizes the risk of disconnection or electrical interference. This robust connection mechanism enhances the overall reliability of the power supply unit in demanding operational environments.
