GE Mark VI IS200EBRGH2AEB Exciter Bridge Interface Board

The EX2100e Excitation Control is GE’s advanced control system designed for both new and retrofit steam, gas, and hydro generators. This cutting-edge system integrates the latest hardware and software design, developed in collaboration with GE’s system and controls engineering teams, to deliver a comprehensive solution. The EX2100e integrates seamlessly with the Mark VIe control system, Mark VI Integrated Control System (ICS), LS2100e Static Starter, and the Human-Machine Interface (HMI). For retrofit applications, the system also supports integration with customer Distributed Control Systems (DCS) via ModBus® Ethernet.

Key Features and Applications

Configurations: The EX2100e is available in various configurations to provide full static and regulator control.
SCR-Based Systems: Uses Thyristor Silicon-Controlled Rectifiers (SCRs) in cell sizes of 42 mm, 53 mm, 77 mm, and 100 mm to meet field current requirements for static applications.
PWM Systems: Features Pulse Width Modulation (PWM) systems with Insulated Gate Bipolar Transistors (IGBTs) to provide outputs of up to 35 A or 120 A for Regulator system applications.

Supported Applications:

Static, potential source (up to 8000 A)
Static, compound source
Alterrex® Regulator system
Saturable Current Transformers/Power Potential Transformer (SCT/PPT) Regulator
Brushless Exciter Regulator
DC Rotating Exciter Regulator
