Features
 GDX series excitation controller only needs one key to start, it can realize automatic excitation control and unattended operation;
◆ Automatically track the grid voltage before the generator is connected to the grid;
◆ After connecting to the grid, it will run according to the set power factor value to achieve constant power factor;
◆ After tripping, the voltage will automatically return to the set value to prevent overvoltage;
◆ Automatically demagnetize when the frequency of the shutdown process is too low;
◆ "Single machine operation" automatically runs according to the set voltage, which can keep the generator voltage constant;
◆ Automatically reduce the excitation (reactive power) when the generator is overcurrent (overcurrent) to prevent the generator from overcurrent;
◆ Low excitation limit to ensure that the generator voltage will not be too low and run in phase;
◆ Can set parameters for unstable excitation operation of special units;
◆ Password protection for setting values to prevent parameters from being modified by unrelated persons;
◆ Equipped with interfaces such as host computer communication to realize computer remote control (optional)
