Industrial-Grade Power Conditioners & Voltage Regulators
Quality Power. Better Business
A power conditioner or automatic voltage regulator (AVR) can correct power quality problems, like brownouts, surges, over-voltage, sags, voltage imbalance, unbalanced current, line noise and others issues that cost business billions of dollars each year. Automatic voltage regulators and power conditioners from UST can correct these power quality problems and help you improve that all-important bottom line.

Industrial-Grade Power Conditioning
All UST power conditioners are rated industrial-grade which not only permits them to be used in the toughest applications but adds that extra measure of confidence in any application. Compared to computer-grade products, industrial-grade products feature:

Industrial-Grade Power Conditioning
All UST power conditioners are rated industrial-grade which not only permits them to be used in the toughest applications but adds that extra measure of confidence in any application. Compared to computer-grade products, industrial-grade products feature:
- Sizing and installation like a dry-type transformer
- Compatibility with all load types
- Overload and fault clearing capability like a transformer
- “Short circuit-proof” and fan-free design
- True high efficiency – not subject to load or application variations
- No de-rating or limitations for low load power factor
- Operation without minimum load limitations
- An output free from added harmonics
- A load-maintaining automatic failsafe bypass
- No scheduled maintenance
