松下蓄電池LC-X12100CH(12V100Ah)充滿電可以供UPS主機延時供電180分鐘讓負載設備緊急處理臨時工作，由于計算機機房設備有各種開關電源類的非線性負載及各類打印機負載，這些負載沖擊電流大，如果供電UPS容量過小，長期重載運行，容易出現波形失真，而且易造成輸出末級功率器件過流，加上重載引起的發熱量，對系統可靠性明顯不利。對于大功率UPS，一般建議容量使用率控制在0.6~0.8。

UPS capacity configuration should take into account the future capacity expansion needs of the equipment, leaving a certain amount of margin, the future load increased, so as not to purchase UPS again.In addition, as far as possible to choose a model with parallel machine function, when necessary through UPS parallel machine multiplied to expand the output capacity.At the same time, when the input and output distribution cabinet of UPS is configured, a certain amount of cable and space should be left to facilitate capacity expansion in the future
