IS200ERDDH1ABA Exciter regulator dynamic discharge board
The IS200ERDDH1ABA has several important functions, including controlling the excitation system of the generator to ensure that the voltage and excitation current are within the required range, thereby maintaining the stability of the power system. In addition, it can also monitor the output voltage of the generator and adjust it as needed to ensure consistency with the voltage of the power network.
At the same time, the device also helps to maintain the output frequency of the generator within the required range to ensure the stability and quality of the power system.
The IS200ERDDH1ABA has two modes of operation: simplex and redundancy. In simplex mode, the model controls the K3 charging relay. In redundant mode, it will control the K41 field out relay. The installation location also varies according to the mode of operation.
The IS200ERDDH1ABA also has the capability to provide feedback from the bridge to observe the output field and DC link voltage, and to control excessive DC link voltage through dynamic discharge of the model.
