PFR-T Power Factor Controllers

The PFR-T power factor controller calculates the active and reactive power in the 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 switchings.At the same time, switching operations are equally shared among the available capacitor branches where possible.The integrated connection control immediately detects in which phase voltage and current are measured, and adapts the entire system automatically.The very low current threshold of 10mA allow for very reliable and exact PF control.1A as well as 5A current transform can be used without additional manual adjustments.The power supply cover a voltage range of 90....550V.
