An Automatic Power Factor Correction (APFC) Panel is an essential piece of equipment for industries and commercial buildings to maintain a healthy power factor. A low power factor can lead to penalties from utility providers, increased energy bills, and a shorter lifespan for electrical equipment. APFC panels automatically monitor and adjust the power factor by switching capacitor banks on or off as the electrical load changes, ensuring that the system operates at maximum efficiency. This proactive correction helps in reducing energy costs and improving overall power quality. Many companies specialize in manufacturing and supplying these panels, with options ranging from standard configurations to custom-built solutions tailored to a client's specific needs. These manufacturers often integrate advanced microcontroller-based relays and high-quality components to ensure reliability, accuracy, and longevity.
