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
Electricity voltage: generator voltage 400V, grid line voltage 400V
Grid identification: Use grid circuit breaker to assist normally open contact
Excitation output: excitation voltage 0～80V (0～180V), excitation current 0～18A (0～20A), when the excitation current exceeds 18A, the controller should have customized capacity Larger thyristor module
