大型企业计算和存储技术的进步要求电源保护技术进行改革。Symmetra是一种由模块化组件组成的单一单元。这种模块化体系结构为构建和扩展灵活的功率容量范围、接近不间断可用性的电源系统奠定了基础。Symmetra?PowerArray结合了APC的全线数据中心保护软件和附件，提供总体数据中心的4个最关键的要素：冗余性、可扩展性、易管理性、易服务性。可用性内置自动旁路在发生电器故障或过载时保证无间断的负载供电热更换电池当更换电池时，保证负载的不间断运行热插拔电子元件当UPS更换电子元件时，保证负载的不间断运行冗余特性在可承受的成本下提供高可用性可扩展性功率扩展能力允许未来的增加和保护初始的投资更长的延时时间满足用户对系统运行时间需要可服务性热插拔电子元件当UPS更换电子元件时，保证负载的不间断运行热更换电池当更换电池时，保证负载的不间断运行内置手动旁路当任一模块或所有的模块更换时，保证负载的供电正常易管理性网络管理"UPS网络接口卡为网络管理员提供机架内、机房内和数据中心环境下UPS的标准模块管理。APCWeb/SNMP卡是唯一的能够通过多种开放式标准如Telnet、HTTP和SNMP来实现管理功能的UPS管理附件。它是特点鲜明的、全新的与企业管理紧密集成的电源管理软件。通过Web/SNMP卡可以监控和配置APCUPS关闭和重新启动计算机系统。"LCD显示控制面板通过LCD显示屏，关键的测量值都能被快速的获得。这些信息包括可用电源、电池参数、输出值和容量百分比。如果告警条件出现，告警声音会出现、红灯会亮，显示屏会显示出现告警的原因。监视器分成不同的功能，任一部分出现问题，都会出现告警。对于电力事件和UPS事件，显示屏会维持以时间为标志的事件记录，通过显示屏获得的事件记录可以更容易的诊断。SmartSlot插槽通过把APC附件卡插在SmartSlot插槽中，用户可以监控UPS电源系统并采取必要的措施。附件卡会提前通知用户某些事件或者某种市电环境将会影响电池的后备时间，从而提高了整个电源系统的可用性(附件卡需另行购买）230VkWatts0.511.522.534567891011完全半负荷kVA~0.71.42.12.83.54.25.678.49.811.212.61415.4负荷负荷SYH2K6RMI43min20min------------------------13min(1400Watts)30min(700Watts)SYH2K6RMI+(1)SYBT21hrs36mins47min------------------------32min(1400Watts)1hrs8mins(700Watts)SYH2K6RMI+(2)SYBT22hrs32mins1hrs15mins------------------------52min(1400Watts)1hrs49mins(700Watts)SYH2K6RMI+(3)SYBT23hrs29mins1hrs44mins------------------------1hrs13mins(1400Watts)2hrs30mins(700Watts)SYH2K6RMI+(4)SYBT24hrs28mins2hrs14mins------------------------1hrs34mins(1400Watts)3hrs13mins(700Watts)SYH4K6RMI1hrs24mins43min28min20min15min------------------13min(2800Watts)30min(1400Watts)SYH4K6RMI+(1)SYBT22hrs10mins1hrs8mins45min32min25min------------------22min(2800Watts)48min(1400Watts)SYH4K6RMI+(1)SYRMXR4B4I4hrs43mins2hrs30mins1hrs40mins1hrs14mins58min------------------51min(2800Watts)1hrs47mins(1400Watts)SYH4K6RMI+(2)SYBT23hrs0mins1hrs35mins1hrs2mins46min36min------------------31min(2800Watts)1hrs7mins(1400Watts)SYH4K6RMI+(2)SYRMXR4B4I8hrs18mins4hrs26mins2hrs58mins2hrs12mins1hrs44mins------------------1hrs32mins(2800Watts)3hrs11mins(1400Watts)kWatts0.511.522.534567891011完全半负荷kVA~0.71.42.12.83.54.25.678.49.811.212.61415.4负荷负荷SYH4K6RMI+(3)SYRMXR4B4I12hrs1mins6hrs26mins4hrs19mins3hrs13mins2hrs33mins------------------2hrs16mins(2800Watts)4hrs38mins(1400Watts)SYH4K6RMI+(4)SYRMXR4B4I15hrs50mins8hrs30mins5hrs43mins4hrs16mins3hrs23mins------------------3hrs0mins(2800Watts)6hrs7mins(1400Watts)SYH4K6RMI+(5)SYRMXR4B4I19hrs43mins10hrs35mins7hrs8mins5hrs19mins4hrs13mins------------------3hrs45mins(2800Watts)7hrs38mins(1400Watts)SYH4K6RMI+(6)SYRMXR4B4I23hrs41mins12hrs43mins8hrs34mins6hrs24mins5hrs5mins------------------4hrs31mins(2800Watts)9hrs11mins(1400Watts)SYH6K6RMI1hrs59mins1hrs5mins44min32min25min20min14min--------------13min(4200Watts)30min(2100Watts)SYH6K6RMI+(1)SYRMXR2B4I3hrs27mins1hrs54mins1hrs17mins58min45min37min26min--------------25min(4200Watts)55min(2100Watts)SYH6K6RMI+(1)SYRMXR4B4I5hrs0mins2hrs47mins1hrs54mins1hrs25mins1hrs7mins56min40min--------------38min(4200Watts)1hrs21mins(2100Watts)SYH6K6RMI+(2)SYRMXR4B4I8hrs15mins4hrs37mins3hrs9mins2hrs22mins1hrs53mins1hrs33mins1hrs8mins--------------1hrs5mins(4200Watts)2hrs15mins(2100Watts)SYH6K6RMI+(3)SYRMXR4B4I11hrs36mins6hrs31mins4hrs27mins3hrs21mins2hrs40mins2hrs13mins1hrs38mins--------------1hrs33mins(4200Watts)3hrs12mins(2100Watts)SYH6K6RMI+(4)SYRMXR4B4I15hrs2mins8hrs27mins5hrs47mins4hrs22mins3hrs29mins2hrs53mins2hrs8mins--------------2hrs1mins(4200Watts)4hrs10mins(2100Watts)kWatts0.511.522.534567891011完全半负荷kVA~0.71.42.12.83.54.25.678.49.811.212.61415.4负荷负荷SYH6K6RMI+(5)SYRMXR4B4I18hrs32mins10hrs25mins7hrs9mins5hrs24mins4hrs19mins3hrs34mins2hrs39mins--------------2hrs30mins(4200Watts)5hrs9mins(2100Watts)SYH6K6RMI+(6)SYRMXR4B4I22hrs5mins12hrs26mins8hrs32mins6hrs27mins5hrs9mins4hrs16mins3hrs10mins--------------3hrs0mins(4200Watts)6hrs8mins(2100Watts)SYH6K6RMI+(7)SYRMXR4B4I25hrs41mins14hrs28mins9hrs56mins7hrs30mins6hrs0mins4hrs59mins3hrs41mins--------------3hrs30mins(4200Watts)7hrs9mins(2100Watts))
