Sag Fighter
The Sag Fighter provides solid, affordable protection for sensitive equipment from deep voltage sags (dips) without batteries or energy storage. Available in size from small three phase applications up to complete facility protection, the Sag Fighter is compatible with all load types and power factors.
The Sag Fighter has no batteries or other parts to replace and requires no regularly scheduled maintenance or monitoring. The 99% electrical efficiency offers huge energy savings when compared to other sag correction products- especially to large-scale applications.
Since the Sag Fighter does not depend on stored energy; it provides sag protection for as long as the sag condition exists. Also, protection from consecutive deep voltage sag events is always available since the Sag Fighter is never offline to recharge or reset.
The Sag Fighter works simply by using additional current to create a properly shaped injection voltage to replace those portions of the voltage waveform that is missing during a sag event. The unit monitors the incoming voltage waveform for any deviation from normal and reacts to correct a sag when the voltage starts falling below 90% of nominal voltage.
