The IS200ERDDH1ABA excitation controller is a device used to control the excitation system of a generator. Its main function is to collect the analog signal in the power system into the control chip, analyze and calculate the current working condition, and then input the calculated excitation control signal into the excitation power module. The excitation power module controls the size and direction of the excitation current according to the size of the input control signal, thus controlling the operation mode of the generator.

The working principle of IS200ERDDH1ABA excitation controller involves sensor detection, signal conversion, control strategy calculation, excitation current signal sending and excitation system response. The sensor first detects the output voltage and current of the generator and converts these signals into electrical signals sent to the controller. After receiving the signal, the controller calculates the required excitation current according to the preset parameters and control strategy, and sends the calculated excitation current signal to the excitation system. The excitation system generates a constant magnetic field by changing the voltage signal and providing direct current to the excitation coil of the generator, which affects the output voltage and current of the generator.
