GDX-series excitation controller only needs one key to start, it can realize fully automatic excitation control and unattended operation!

GDX-D2 intelligent excitation controller is a special product for brushless excitation generator with terminal voltage of 400V. UsersFreeModify the excitation operation parameters,  is the most advanced at present One of the excitation controllers.

◆Generator After grid connectionAutomatically track grid voltage;

◆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;

◆Automatic identification of shutdown process and de-excitation control;

◆"Single machine operation" automatically runs at the set voltage during operation, which can keep the generator voltage constant;

◆The parameters can be set especially for units whose excitation operation is unstable;

◆Automatically reduce the excitation (reactive power) when the generator is overcurrent (overcurrent) to prevent the generator from overcurrent;

◆Setting value password protection to prevent parameters from being modified by unrelated personnel;
     ◆Equipped with a host computer communication interface to realize computer control (optional match).

▲Applicable to brushless excitation synchronous generator with terminal voltage of 400V.

▲Applicable to GDX-2 excitation controller: excitation voltage 0～180V excitation current 0～20A< /span>

◆Input Signal:

Electrical    current:  rated current 5A, connected via current transformer
