The power factor controller DNKL-12J/D paralleled with capacitor to control the automatic switching of capacitor compensation, improve the power factor and power transformer utilization efficiency and reduce the loss.

The power factor controller calculates the active and reactive power in mains from the measured current and voltage. The intelligent control algorithm optimizes the switching sequences and guarantees for short regulation times with minimum number of switching. At the same time, switching operations are equally shared among the available capacitor branches where possible. The integrated connection control immediately detects in which phases voltage and current are measured, and adapts the entire system automatically. The very low current threshold of 10mA allows for very reliable and exact PF control. 1A as well as 5A current transformers can be used without additional manual adjustments. The power supply covers a voltage range of 100V-220V.
