IS200ERDDH1A Excitation regulator dynamic discharge board
The IS200ERDDH1A is an exciting regulator dynamic discharge board from General Electric. The product works in two modes: single mode and redundant mode. In a single mode, the model controls the K3 charging relay. In redundant mode, it will control the K41 field out relay. The installation position varies by mode. In simplex mode, the IS200ERDDH1A is installed in the ERBP backplane. In redundant mode, two ERDD models need to be used, one mounted on the ERBP backplane and one mounted on the ERRB backplane.
Its functions mainly include:
Dynamic discharge control: The IS200ERDDH1A can control the high DC link voltage through dynamic discharge to ensure the stable operation of the system.
Relay control: In simplex mode, the board controls the K3 charging relay; In redundant mode, it will control the K41 field out relay.
Monitoring function: The board allows observation of the output shunt current, IGBT gate drive status and bridge temperature, as well as providing feedback from the bridge to observe the output field and DC link voltage.
Easy installation and maintenance: The design of the IS200ERDDH1A makes it easy to install and maintain, while the modular system makes it suitable for a variety of applications.
Other features: In addition to the above features, the IS200ERDDH1A may also have other features, such as easy service, precision operation, testing and connecting components, which make debugging and maintenance easier.
