The Power-Sure 700 Three Phase Power Line Conditioning system provides exceptional system reliability that can be attributed to MGE's microprocessor controlled zero-current cross tap switching technology. The Power-Sure 700 combines solid state, microprocessor based voltage regulation, with a multi-shield computer grade transformer and filter to remove transients and noise. The combined effect is a regulating and shielded isolation transformer/system that solves 99% of the electrical disturbance problems. The Power-Sure 700 protects your system against electrical brownouts, sags, surges, transients and other electrical disturbances. This power conditioner also provides the protection, efficiency, and reliability that are critical to every application with sensitive equipment.
