An 'Automatic Capacitor Panel Manufacturer' is a company that specializes in the design, engineering, and production of panels that automatically correct the power factor of an electrical system. These panels are also commonly known as Automatic Power Factor Correction (APFC) panels or Automatic Capacitor Banks. The core function of these panels is to improve power quality and efficiency by monitoring the power factor in real-time and dynamically switching in or out capacitor banks to counteract the 'reactive power' drawn by inductive loads such as motors, transformers, and large machinery. By doing so, they ensure the power factor stays close to the ideal value of 1.0, which leads to reduced energy waste and avoids penalties from utility companies.
