Trinity Power Factor Controllers (APFC relays) are intelligent, RMS-based devices that manage reactive power by switching capacitor banks in real time. With programmable PF targets, site-configurable inputs, accurate VAR-based control, and robust performance, they offer reliable, cost-effective PF correction for industrial, commercial, and renewable energy systems.

Description
The Trinity Power Factor Controller, also called an APFC relay, is a smart device that monitors your electrical system’s power factor and automatically switches capacitor banks accordingly. Equipped with true RMS measurements and microcontroller-based logic, it maintains efficient power usage by dynamically adjusting reactive power and minimizing utility penalties. Variants like APFCR, Newton+, and AccuVar offer a spectrum of features from economy models to advanced, fast-switching units. Trinity Energy+1
