An automatic power factor correction (APFC) panel is a crucial component in electrical systems designed to optimize the power factor, thereby improving energy efficiency.

Its main function is to automatically monitor the power factor of the connected electrical load and then control the operation of power factor correction capacitors to maintain an optimal power factor close to unity. This ensures that the reactive power in the system is minimized, leading to reduced losses and increased overall energy efficiency.

The APFC panel continuously analyzes the power factor in real-time and adjusts the capacitors accordingly, providing a cost-effective solution to enhance the power quality, reduce electricity bills, and prevent penalties associated with poor power factor performance. Additionally, these panels often come equipped with advanced control systems, protection mechanisms, and user-friendly interfaces, making them a reliable and efficient solution for power factor optimization in various industrial and commercial applications.
