The Thermonic Automatic Power Factor Correction (APFC) Panel is an intelligent system designed to maintain the power factor of electrical networks automatically. It continuously monitors reactive power consumption and switches capacitor banks in or out using microprocessor-based APFC relays to achieve the desired power factor, thus improving energy efficiency and reducing penalties from electricity boards.
Ideal for industries, commercial buildings, and utilities, the Thermonic APFC Panel ensures optimum utilization of electrical power, reduces system losses, and enhances the lifespan of equipment. It supports both manual and automatic operation modes with precision control and reliable protection features.
