Leading Power Factor Controller Manufacturers offering advanced controllers for accurate power factor correction, energy savings, and reliable performance in APFC panels.
A power factor controller, also called an APFC relay, is the brain of every automatic power factor correction panel. It measures the power factor of your supply many times a second, compares it with the target you have set, and switches capacitor steps in or out to keep the two together. RuncoN, a brand of Maurya Enterprises, is an ISO 9001:2015 certified power factor controller manufacturer based in Jhilmil Industrial Area, Delhi.
As a reliable manufacturer, we have developed microprocessor-based controllers that detect even a small change in load current and instantly switch the capacitor banks accordingly. They help industries, commercial buildings and utilities hold a steady power factor, avoid wasted energy and escape penalty charges from the electricity board.
The controller takes a current signal from a CT on the incoming supply and a voltage signal from the line. From these it calculates the power factor and the reactive power (kVAr) still needed to reach the target, usually set between 0.95 and 0.99. It then picks the right combination of capacitor steps, energises the capacitor-duty contactors, and waits for the set delay before checking again. Because the loop runs continuously, the correction follows your load as motors start and stop through the day.
Our controllers combine accurate sensing with practical features that panel builders and maintenance teams use every day:
These features ensure accurate control of capacitor switching, so the power factor is neither over-corrected nor under-corrected, even when the load changes quickly.
Our controllers are compact, easy to wire and compatible with standard, heavy-duty and detuned capacitor banks. A clear terminal layout and standard panel cut-out make installation quick for panel builders and electricians. Whether you are building a new APFC panel or replacing a faulty relay in an existing one, the controller drops in without major changes to the panel.
Send us your capacitor step list and load details and we will recommend the right controller. You can also size your bank with our kVAr calculator, or see our APFC relay range.
