LT APFC Panel

Automatic Power Factor Correction Panel

LT APFC Panel

Product Overview

The LT APFC Panel (Low Voltage Automatic Power Factor Correction Panel) by Domain Powers is engineered to deliver consistent power factor above 0.99 in 415V / 440V industrial electrical systems. Designed with industrial grade PFC components and precision control technology, our LT APFC panels ensure maximum penalty savings, reduced kVA demand and long operational life even under demanding load conditions. Built for Indian power conditions, fluctuating loads and heavy motor applications, our LT APFC panels provide stable, intelligent and reliable power factor correction for industries and commercial facilities.

Technical FAQs

What is an LT APFC Panel?

An LT APFC Panel is an electrical system used in 415V / 440V three-phase networks to automatically maintain power factor by switching capacitor banks based on real-time load conditions.

What voltage is an LT APFC panel used for?

LT APFC panels are designed for 415V / 440V low voltage three-phase electrical systems commonly used in industrial and commercial installations.

What power factor can be achieved?

A properly engineered LT APFC panel can maintain a stable power factor between 0.98 and 0.99, depending on load variation and system conditions.
