IS200ERDDH1A

The IS200ERDDH1A is a GE EX2100 and EX2100e Exciter Regulator Dynamics Discharge Board used in generator excitation protection applications. This board manages the dynamic discharge of the generator field winding when the EX2100 excitation system trips or shuts down, providing a controlled dissipation path for stored magnetic energy in the generator rotor field. Proper dynamic discharge is critical for rotor protection — uncontrolled collapse of field energy can generate damaging overvoltage spikes in the rotor circuit. A failed IS200ERDDH1A compromises this protection function and represents a significant risk to the generator during excitation trip events. Powergenics repairs and supplies the IS200ERDDH1A with a 3-year warranty. Call 800-861-9773.
