Line Reactor

Description

A Line Reactor (also known as an AC Reactor or Input Reactor) is an inductive device installed at the input of Variable Frequency Drives (VFDs), inverters, or other sensitive equipment to limit harmonics, reduce inrush current, and protect against voltage spikes. It improves power quality, extends the life of drive components, and ensures smoother operation of electrical systems.
