GE IS200ERDDH1ABA EX2100励磁控制器

产品描述
IS200ERDDH1A型号是EX2100系列的一部分，是一个励磁调节器动态放电板。ERDD模型有简单和冗余两种工作模式。每种应用程序模式的使用方式和挂载方式都不同。

当IS200ERDDH1A在单工模式下使用时，该模型控制K3充电继电器;当电路板在冗余模式下使用时，它将控制K41去磁继电器。当工作在单工和冗余模式时，ERDD模式的安装位置是不同的，当工作在单工模式时，IS200ERDDH1A安装在ERBP背板上，当工作在冗余模式时，必须使用两个ERDD模型，一个与单工模式下的模型安装在相同的位置，另一个板将安装在ERRB背板上。

电路板的另一个功能是提供来自电桥的反馈，以观察输出场和直流链路电压。当监测这些板也允许观察输出分流电流，IGBT栅极驱动状态，和桥的温度。IS200ERDDH1A板通常也用于通过模型的动态放电来控制多余的直流链路电压。

Product Description
The IS200ERDDH1A model is part of the EX2100 series and is an Exciter Regulator Dynamics Discharge Board. The ERDD model has two operating modes, simplex and redundant. Each application mode is used differently as well as mounted differently. 

When the IS200ERDDH1A is being used in simplex mode the model controls the K3 charging relay; when the board is being used in the redundant mode it will control the K41 de-excitation relay. The mounting places of the ERDD mode when operating in simplex and redundant mode are different, when in simplex mode the IS200ERDDH1A is mounted in the ERBP backplane and when in redundant mode two ERDD models must be used, one is mounted in the same location as the model in simplex mode and the other board will be mounted in the ERRB backplane. 

Another function of the board is to provide feedback from the bridge to observe the output field and DC link voltages. When monitoring these the board also allows for observation of output shunt currents, IGBT gate drive statuses, and bridge temperature. The IS200ERDDH1A board is also typically used to control the excess DC link voltages through the dynamic discharge of the model.
