Low-Voltage Dnkl Series

Functional feature

The DNKL series reactive power compensation intelligent controller uses a high-speed microprocessor as the control core, which has powerful functions,strong anti-interference ability,and fast operation speed. The product is manufactured using surface mount technology and is matched with parallel capacitor devices to control the automatic switching of compensation capacitors, thereby improving power factor, enhancing the utilization efficiency of power transformers, reducing line losses, and improving power quality.The controller uses voltage (U)or reactive power (Q)as the control physical quantity (which can be flexibly selected according to customer needs), and can meet the needs of different users.

 This product is suitable for capacitor compensation in box type substations and standard screen structures.

According to the different compensation methods of capacitors, this controller has two types to choose from:hybrid compensation and fully balanced compensation, with corresponding numbers of 3 and 1 current transformers, respectively.
