What is an APFC Panel?
Automatic Power Factor Correction for efficient electrical systems
An APFC panel (Automatic Power Factor Correction) maintains your system power factor at optimal levels—typically above 0.98—using intelligently switched capacitor banks. This reduces power factor penalties, unloads transformers, and improves overall electrical efficiency for your facility.
Voltaire APFC Panels use microcontroller-based relays, detuned reactors, and heavy-duty capacitor banks to manage reactive power dynamically. This ensures stable operation even in networks with harmonics, fluctuating loads, and mixed motor plus electronic loads.
The result is simple: fewer penalties, lower losses, and a healthier electrical system for manufacturing plants, commercial complexes, hospitals, data centers, and OEM power distribution schemes.

Why Power Factor Correction Matters
Reduce penalties, protect transformers, and improve efficiency
APFC panels are not just about meeting utility norms. They are a fundamental part of a healthy electrical system where motors, drives, and sensitive electronics can operate reliably.
Reduces PF penalties
Avoid recurring charges from low power factor and improve your monthly energy bills.
Prevents transformer overload
Lower reactive current flow helps keep transformer loading within safe limits.
Improves machine efficiency
Stable, optimised PF reduces heat losses and electrical stress on motors and drives.
Reduces line losses
Lower current for the same active power reduces copper losses in cables and busbars.
Stabilises voltage profile
Reactive power management helps maintain better voltage levels across distribution.
Supports expansion plans
Good PF can free up capacity in existing transformers for future loads.
