Numerous companies specialize in the manufacturing of Automatic Power Factor Correction (APFC) panels, which are essential for maintaining a high power factor and ensuring energy efficiency in industrial and commercial electrical systems. These manufacturers, such as Next-Gen Power Controls, Hindustan Power Control System (HPCS), and Adroit Control Engineers, design panels with sophisticated features. Their products often integrate microprocessor-based controllers that continuously monitor the power factor and automatically switch capacitor banks on or off to compensate for reactive power. This process prevents penalties from electricity boards, reduces energy losses, and extends the lifespan of electrical equipment. Many of these companies offer customized solutions and a range of panel types, including those with detuned filters for environments with high harmonic distortion, catering to a wide variety of applications from small commercial setups to large industrial plants.
