Automatic Power Factor Correction (APFC) panel manufacturers design and build panels that automatically improve the power factor of an electrical system. These companies create panels with an intelligent controller that monitors reactive power and switches capacitor banks on or off as needed. Leading manufacturers like Schneider Electric, ABB, and BCH are known for producing robust, efficient, and reliable APFC panels. Their solutions help businesses reduce electricity bills, avoid penalties from utility companies, and enhance the overall efficiency of their electrical infrastructure
