Uninterruptible Power Systems: Operational and Cost Considerations.

Abstract

A study of cost and potential benefits of Uninterruptible Power Systems (UPS) for Air Force communication systems was made, using data from four specific systems. An important conclusion was that UPS justifications should not be based on marginal increased in power availability but upon requirements for 'clean' power needed by modern computers and other devices using low-voltage, low-power logic circuits. Such circuits may be particularly susceptible to transients, surges, dropouts, overvoltages and undervoltages (brownouts) which are common anomalies of power furnished by public utility companies. UPS may be needed more to clean up 'dirty' power during the 99+% of time it is available, than to furnish power during prime-power outages. (Author)
