                                          What It Does (Simple Explanation)

                                          The DECS-100 continuously monitors the generator output voltage.

                                          Working process:

                                          1. Generator voltage is measured.
                                          2. The controller compares actual voltage with the preset value.
                                          3. Excitation current is automatically adjusted.
                                          4. Generator voltage remains stable despite load changes.
                                          5. Built-in protection monitors abnormal operating conditions.

                                          This improves generator stability, especially when operating independently or in parallel with other generators or the utility grid.
