本讲座主要内容 第一部分:节能环保型不间断电源—ISPS(超级UPS) 第二部分:不间断电源系统的科学配置 第三部分:现代工业用应急电源—MEPS一、ISPS 基本功能简介1.1 ISPS工作模式(选摸式/定摸式)"选模式"可选择系统在"U"(UPS)或"E"(EPS)或"I"(ISPS)模式下工作."I"为节能环保模式."定模式"即无选择地工作在"I"模式下.工况为:当市电参数正常时,ISPS系统直接输出市电;当市电参数异常时,ISPS系统对市电进行处理后再输出;当市电因故将要停电时,ISPS系统根据扑捉信息的判断,提前将负荷快速转换到应急电源供电,实现无缝切换;对于无法提前监测的人为停电,系统将快速跟踪断电信号并在2ms-10ms内完成快速转换;对于计划停电,可设定自动转换时刻,按时无缝切换.
