The Eaton® Power-Sure TM 700 three-phase power line conditioning system provides exceptional system reliability that can be attributed to Eaton''s processor-controlled zero-current cross tap switching technology. The Power-Sure 700 combines voltage regulation with a transformer and filter to remove transients and noise. The combined effect is a regulating and shielded isolation transformer/system that solves 99 percent of the electrical disturbance problems, including electrical brownouts, sags, surges, transients and other electrical disturbances. This state-of-the-art power conditioner also provides the protection, efficiency and reliability that are critical to every application with sensitive equipment.Features Processor controlled voltage regulation Tight output voltage regulation Zero-current switching Wide input regulation range Triple shielded, computer grade transformer Highly efficient -97 percent typical High inrush capability Transient protection and high frequency filter Over/under voltage protection (optional) Includes input circuit breaker Manual bypass switch (optional)
