• Is the ferroresonant technology an old or outdated technology?
  • No. Although it has been around for over 40 years, its reliability and performance have not been surpassed by any other technology. Ferroresonant technology offers trouble-free, clean regulated power and a product life expectancy of over 20 years.
• Are all tap switching power conditioners the same?
  • No. There are different design approaches that change the overall performance and efficiency. Controlled Power Company uses the most conservative designs, providing the widest input operating voltage range, tightest output voltage regulation, and the greatest efficiency.
• Is it true that ferroresonant transformers must be partially loaded to function correctly?
  • This depends upon the design. Some manufacturers design their transformers in a way that the load current is an integral part of the operation to conserve copper. The Commercial Power Purifier operates from 0% to 100% load while maintaining its tight regulation without overheating. Pre-load planning is not required.
• Is it true that the MTBF is 200,000 hours?
  • Yes! The transformer is constructed with high-grade silicon steel and electrical grade copper. The vacuum impregnation process assures mechanical stability, and with the low component count, 200,000 hours is easily obtained.
• Just what is VRR?
  • VRR stands for “Variable Range Regulation.” This unique feature extends the input operating range from -20% at 100% load to -40% of nominal at 50% load. That equates to 72 volts on a 120 volt nominal input, while maintaining a regulated AC sine wave output.
• Does the Commercial Power Purifier really correct power factor and attenuate harmonics?
  • Yes. The Power Purifier corrects power factor at the input and improves it for the load as well. The filtering properties of output transformer reduce reflected harmonics to typically 5% or less at the input.
• Will the Commercial Power Purifier handle a short circuit?
  • Yes. If a short circuit occurs on the output of the Commercial Power Purifier, the unit will limit the current and the output voltage will drop to near zero. The output will return to full nominal voltage once the short is cleared via an output fuse or breaker. No damage will occur to the Power Purifier.
• Can the Commercial Power Purifier be used in medical applications?
  • In many applications, yes. The Power Purifier's leakage to ground current (1 kVA - 3.5 kVA) is measured at less than or equal to 20 microamps. While the Commercial Power Purifier is not UL listed to 60601-1, its measured leakage current to ground is well below the maximum level specified within the UL Standard. In addition, 15 amp or 20 amp hospital-grade input plug and output receptacles are available upon request.

Controlled Power Company warrants the Series 800A Commercial Power Purifier to be free from defects in material and workmanship for a period of 10 years on the transformer (core and coil), and 2 years on all other unit components. Controlled Power Company agrees to replace, F.O.B. its factory, any parts which fault through defect in material or workmanship during the warranty period.

Warranty begins from date of shipment unless a factory start-up is purchased, then the warranty begins from date of start-up or 90 days from ship date; whichever comes first.

Consult the factory for additional warranty details, and a description of start-up services provided.
