FKJ-GT (Grid-tie) model Product Characteristics

◆The product is manufactured according the JB/T6939.1-2004 industrial standard and GB/T 19115.1-2003 national standard also with users’ technical requirements.

◆Two sets of control systems：PWM constant voltage system and three-phase dump load system.

◆The big screen LED display. Clearly present the DC output voltage.

◆PWM constant voltage control is 120% of the rated power of the wind turbine. In case exceeding of PWM’s capacity, the three-phase dump load will automatically start immediately. After 10-20 minutes, the three-phase dump load will stop and the wind turbine will re-start to resume power supply to ensure the safe running of the overall wind turbine generation system.

◆When the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the inverter safety running.

◆When the condition of disconnected grid-connected inverter, the controller can conduct constant voltage output and wait for inverter resumption.

◆When the grid is cut off, the three-phase dump load of the controller will automatically start to work and the inverter will stop output to grid. When the grid resuming, the controller stops three-phase dump load and the inverter will resume power supply.

◆For the different wind turbine, the controller can be equipped with mechanical yawing, furled empennage, mechanical brake, hydraulic brake, electromagnetism brake and other brake functions.

◆The inside of the controller is equipped with surge arrester. Contain the over voltage into the wind turbine under the bearable voltage of the equipment or system. On another way, to conduct the strong lightening current into the earth directly to avoid any damage of equipment.

◆The controller is equipped with emergency stop switch; in case of emergency, press down the emergency stop button in the front panel to cut off all power supply of the controller and the wind turbine will immediately brake（three-phase dump load）.

◆The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will brake (three-phase dump load).

◆Optional communication Mode：RS232、RS485、GPRS、USB、RJ45 ect, Can monitor multiple devices running.
