Numerous companies specialize in the manufacturing of Automatic Power Factor Correction (APFC) panels, which are essential for optimizing electrical efficiency and preventing utility penalties. These manufacturers, such as Next-Gen Power Controls, Adroit Control Engineers, and Hindustan Power Control System (HPCS), design and produce panels that utilize advanced technology. Their products typically feature a microprocessor-based controller that continuously monitors the power factor and automatically switches banks of capacitors on or off to compensate for reactive power. Many of these companies also offer panels with detuned filters to mitigate the damaging effects of harmonics, which are prevalent in industrial settings. By providing customized solutions for a wide range of applications, these manufacturers help businesses reduce their energy consumption, lower electricity bills, and extend the operational life of their electrical equipment.
