When guaranteed real-time access and reaction are required of a critical system, an uninterruptible power system is a must. Most large-scale computer and control systems used in such critical applications as airline ticket reservations, air traffic controllers, and chemical processing plants are provided with redundant elements, automatic reconfiguration, or other safeguards to assure that data processing is not interrupted by computer element failures. But despite such precautions, these systems are still subject to commercial power system problems. Regulating transformers and similar devices can help a data system coast over short power transients but, for full protection, an uninterruptible power system (UPS) is needed.
