Comparing UPS System Design Configurations [OG Partner]
Although the public power distribution system is fairly reliable in most developed countries, studies have shown that even the best utility systems are inadequate to meet the needs of mission-critical applications. Most organizations, when faced with the likelihood of downtime, and data processing errors caused by utility power, choose to implement an uninterruptible power supply (UPS) system between the public power distribution system and their mission-critical loads. The UPS system design configuration chosen for the application directly impacts the availability of the critical equipment it supports. There are many variables that affect a system’s availability, including human error, reliability of components, maintenance schedules, and recovery time. The impact that each of these variables has on the overall system’s availability is determined to a large degree, by the configuration chosen.
