The Promoda Automatic Power Factor Correction (APFC) Panel is designed to improve the power factor of electrical systems by automatically controlling capacitor banks in response to changing load conditions. The panel helps industrial facilities maintain an optimal power factor, reducing energy losses and avoiding penalties imposed by utility providers.
In industrial electrical systems, inductive loads such as motors, transformers, and compressors often cause the power factor to drop below acceptable levels. A low power factor results in higher current draw, increased power losses, and reduced electrical system efficiency. The APFC panel continuously monitors the power factor of the system and automatically switches capacitor banks to compensate for reactive power demand.
The system incorporates a microprocessor-based power factor controller that analyzes system parameters and activates capacitor stages accordingly. This ensures that the power factor is maintained within the desired range while preventing overcompensation.
Promoda APFC panels are equipped with heavy-duty capacitor banks, capacitor contactors, detuned reactors (optional), and protection devices to ensure safe and efficient operation. The capacitor banks are switched in stages to match load conditions, enabling precise power factor correction.
The panel is constructed using a floor-mounted sheet steel enclosure with modular compartments for capacitor stages and control equipment. Proper ventilation and thermal management ensure safe operation of capacitor banks even in high-load industrial environments.
Designed for 415V low voltage electrical systems, the APFC panel integrates easily with PCC panels and distribution systems. The panel helps improve energy efficiency, reduce system losses, and maintain stable voltage levels within industrial power networks.
Promoda APFC panels are widely installed in manufacturing plants, commercial complexes, infrastructure projects, and power-intensive industries where maintaining power quality and reducing electricity costs are essential.
