An APFC (Automatic Power Factor Correction) Panel is a specialized electrical panel designed to improve power factor by automatically regulating the reactive power in an electrical system. It consists of capacitor banks, contactors, relays, and a microcontroller-based power factor controller that monitors and adjusts the power factor in real time. APFC panels help reduce energy losses, avoid penalties imposed by utility providers for poor power factor, and enhance the overall efficiency of electrical systems. These panels are widely used in industries, commercial buildings, and power distribution networks to ensure stable and cost-effective power usage.
