Is the ferroresonant technology an old or out-dated technology?
No. Although it has been around for over 40 years its reliability and performance has not been surpassed by any other technology. Ferro-resonant technology offers trouble free, clean regulated power with a life expectancy of over 20 years. • Are all ferroresonant systems the same? No. There are different design approaches that change the overall performance and efficiencies. Controlled Power uses the most conservative designs, providing the widest operation range and the greatest efficiency. • Is it true that ferroresonant systems must be properly loaded to function correctly? This depends upon the design. Some manufacturers design the transformers such that the load current is an integral part of the operation to conserve copper. The Power Purifier operates from 0 to 100% load while maintaining its tight regulation and without overheating. Preloading is not required. • Is it true that the Power Purifier can withstand a short circuit? Yes, the Commerical Power Purifier will operate in
