Industrial Power Purifier (500VA - 25kVA)

The Industrial Power Purifier (Series 800PI / 800P2 / 800P3) is a self-regulating, constant voltage transformer which provides isolation and protects against fluctuating voltages, brownouts, line noise, and short-duration power outages. The Industrial Power Purifier's power conditioning properties enable it to attenuate voltage spikes and reduce harmonic input current to less than 9% THD. This product is ideal for any electrical environment, but is especially valuable in industrial applications where high-power equipment can interfere with vulnerable electronic controls. The Industrial Power Purifier delivers isolated, regulated, transient-free, and noise-free sinewave power; thus enhancing the industrial equipment's reliability. It is available in NEMA1, NEMA2, and NEMA 3R enclosures.

Single Phase Sizes: 500VA, 750VA, 1kVA, 1.5kVA, 2.0kVA, 2.5kVA, 3.0kVA, 5.0kVA, 8.0kVA, 10kVA, 15kVA, 20kVA, 25kVA

  • Is ferroresonant technology old or out-dated?

  • No. Although ferro-resonant technology has been around for over 40 years, its reliability and performance have not been surpassed. Ferro-resonant technology offers trouble-free, clean, regulated power.

  • Are all ferroresonant systems 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 operating range and the greatest efficiency.

  • Should ferroresonant systems be properly loaded in order 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 Industrial Power Purifier operates from 0% to 100% load while maintaining its tight regulation, without overheating. Pre-load planning is not required.

  • Can the Industrial Power Purifier withstand a short circuit?

  • Yes, the Industrial Power Purifier will operate in a short circuit condition provided that there is UL required over current protection.

  • Are ferroresonant systems as inefficient as rumors claim?

  • Typically, the Industrial Power Purifier has a 90% to 92% efficiency rating.

  • What is the Industrial Power Purifier's MTBF?

  • The Mean Time Between Failure (MTBF) is approximately 200,000 hours. The transformer is made with high-grade silicon steel and electrical-grade copper. The vacuum impregnation process assures mechanical stability. With few components that might fail, 200,000 hours of operation is easily possible.

  • What is VRR?

  • VRR is Variable Range Regulation, which extends the input operating range to near -40% of nominal. That equates to 72 volts input on a 120 volt nominal, with regulated AC sinewave output.

  • Does the Power Purifier correct power factor and attenuate harmonics?

  • Yes, power factor is corrected at the input power, and is improved it for the load also. The high pass filter in the output reduces reflected harmonics to typically 10% or less at the input.

  • Do any other power conditioning technologies attenuate electrical noise?

  • Some TVSS manufacturers claim power conditioning, but offer no immunity to waveform distortion or momentary loss of power. Their products only attenuate the voltage excretions that exceed limits 25% above nominal. The Industrial Power Purifier fills in the notches, recreates a new sinewave, and regulates the power to a safe limit of a maximum of 3% from nominal.
