Low-Voltage Series Reactors (Detuned Reactors)

XDTH Series

Detuned reactors, connected in series, are necessary for circuits with high harmonic currents. These “series reactors,” usually part of a power factor correction (PFC) capacitor bank, help to reduce harmonics in currents, increase power efficiency, and prevent disasters caused by resonance.
