The PFR‑12 Reactive Power Compensation Controller is a smart 12‑step power factor (APFC) relay that maintains target cosφ and reduces penalty charges in commercial and industrial panels across Pakistan. It continuously monitors PF, voltage, and current via a CT and then switches capacitor steps automatically to correct lagging or leading PF. Setup is straightforward: set CT ratio, target PF, switching mode, and delays using the front keys and clear display.
Optimized algorithms reduce hunting and contactor wear, while protections such as over/under‑voltage, step inhibit, and harmonic lockout (model dependent) enhance reliability. The PFR‑12 supports 230/400 VAC, 50/60 Hz systems and provides 12 relay outputs to drive capacitor contactors or thyristor modules. Status LEDs and alarms make diagnostics fast.
