Series 800PI Industrial Power Purifier (500 VA - 25 kVA)
The Series 800PI Industrial Power Purifier is a self-regulating, constant voltage transformer designed to deliver stable, clean power in the most demanding environments. It provides isolation and safeguards against fluctuating voltages, brownouts, line noise, and short-duration outages while delivering “ride-through” protection for up to one cycle. By attenuating voltage spikes and reducing input current harmonics to less than 5% THD, it ensures reliable operation of sensitive electronic controls. Ideal for industrial facilities, it protects critical equipment, reduces downtime, and enhances long-term performance.
Features
- Comprehensive Power Protection – Protects sensitive electronics from power line disturbances, transients, and line noise, ensuring consistent performance.
- Ride-Through Capability – Provides up to one full cycle of backup during short-duration outages, reducing equipment resets or failures.
- Harmonic Mitigation – Acts as a large filter, reducing reflected harmonics and keeping input current distortion below 5% THD.
- Enhanced Equipment Reliability – Solves common power-related issues that lead to downtime, improving longevity and efficiency of connected systems.
- Variable Range Regulation (VRR) – Expands input voltage operating range as load decreases, allowing stable output even during deep sags.
- Tight Voltage Regulation – Delivers output within ±2% typical, ensuring precise power quality for sensitive controls.
- Flexible Installation – Available in NEMA 1, NEMA 2, and NEMA 3R enclosures for indoor and outdoor use across multiple industries.
- Durable, Efficient Design – Provides 90–92% efficiency at full load and operates reliably in temperatures from -20°C to +40°C.

FAQs
Is ferroresonant technology old or outdated?
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.
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 Industrial Power Purifier operates from 0% to 100% load while maintaining its tight regulation without overheating. Pre-load planning is not required.
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 obtained.
Does the Power Purifier correct power factor and attenuate harmonics?
Yes. Power factor is corrected at the input and is improved for the load as well. The filtering properties of output transformer reduce reflected harmonics to typically 5% or less at the input.
Are all ferroresonant transformers 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.
Will the Industrial Power Purifier handle a short circuit?
Yes. If a short circuit occurs on the output of the 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 a downstream fuse or breaker. No damage will occur to the Power Purifier.
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.
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 voltage spikes that exceed limits 25% above nominal. The Power Purifier attenuates voltage spikes down to the fundamental waveform, fills in the notches, recreates a new sine wave, and regulates the output voltage to within 2-3% from nominal.
