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

INTRODUCTION

ZKJ-H 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 systemsPWM constant voltage system and three-phase dump load system.

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.

Under the strong or super-strong wind conditions, the controller can conduct constant voltage output to ensure the Water boiler safety running.

The three-phase dump load of the controller will automatically start and the Water boiler will stop work when the power grid is off. As soon as the grid power resuming, the controller stops three-phase dump load and the Water boiler will resume work.

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 below LED status indication can be found on the front panel: indications of wind turbine, dump load, three-phase dump load delay time, under pressure, grid power and DC output voltage.

Voltmeter indication: Indicate the controller DC output voltage.

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 carry out three-phase dump load.

The controller is equipped with manual three-phase dump load switch. To using this switch, the wind turbine will carry out three-phase dump load forcibly.
