JKL / JKW/ JKGPJ Seris Power Factor Correction Controller (Reactive Power Compensation Controller)
JKL, JKW and JKGPJ series power factor correction (PFC) controllers are intelligent automatic control devices specially designed for low-voltage reactive power compensation systems. They can real-timely detect power factor, voltage and current of power grid, and automatically switch capacitor banks in groups to realize dynamic reactive power compensation.
JKL is for general workshops with light harmonic load; JKW is optimized for harsh working conditions with many frequency converters and strong harmonics; JKGPJ adopts independent split-phase control, specially for three-phase unbalanced load occasions.
With high anti-interference performance, high measurement accuracy and stable operation, this series is widely matched with capacitors, reactors and composite switches. All products comply with IEC – 61921 standards and hold CE certificates, perfectly applicable to 50/60Hz, 380/400V power grids in Vietnam, Europe and Southeast Asia.
