Power Conditioner When the equipment being protected requires an ultra clean source of power, power conditioners are used. These incorporate a low impedance isolation transformer that limits not only peak voltage (amplitude), but also the edge-speed (frequency) of electrical transients (spikes, surges, brown-outs). Featuring a unique grounding methodology that creates a noise-free power supply these provide the highest levels of protection without battery backup.
