Smart APFC relays for accurate capacitor control, stable power factor, and improved energy efficiency in electrical panels.
An Automatic Power Factor Controller (APFC) Relay is the core component of an APFC panel, responsible for monitoring and maintaining the power factor by automatic capacitor switching. As trusted APFC Relay Manufacturers, we design relays that continuously measure voltage and current through CT inputs and calculate real-time power factor. Based on load conditions, the relay activates or deactivates capacitor steps to keep the power factor close to unity.
Our APFC relays are built with advanced microcontroller technology, digital displays, and programmable parameters for precise control. They support multiple step outputs, CT ratio settings, switching programs, alarms, and protection features. Designed for stable performance under fluctuating loads, these relays ensure fast response time, accurate sensing, and long operational life in demanding electrical environments.
APFC relays are widely used in APFC Panels, PCC Panels, MCC Panels, and power distribution boards in industries, commercial complexes, hospitals, hotels, and data centers. They help reduce electricity penalty charges, improve voltage stability, and enhance overall energy efficiency by maintaining optimal power factor.
