Symmetra PX                              　      
  　　　　　　　  

　 大型公司计算和存储技术的进步，越来越多的的电源的需求，要求电源保护技术随之而变化。Symmetra PX 由模块化的部件构成，它具有3相输入、3相输出，这种模块化结构，为构建和衡量一个几近永不间断，同时又具备灵活的电源容量范围的高可用电源系统奠定了基础。Symmetra PX 将方便升级的电源容量和电池后备运行时间等高可用性需求，集成到占地面积非常小的机柜空间中，配合APC全线数据中心保护管理软件和附件，为数据中心保护提供4个最关键的基础。

可用性 

• 冗余特性 添加其它电源模块的能力提供了 N+1 冗余并且增强了解决方案的可用性。 

• 更长的延时时间 能够添加更多的电池，以便在供电发生故障时延长为负荷供电的时间。 

• 内置静态旁路开关 The built-in static bypass switch enables the UPS to transfer the load to utility power, without interruption, in case of heavy overload or faulty conditions. 

经济性 

• 全额定电源，kVA 等于 kW。 Symmetra PX 的全额定反向变流器非常适用于今天功率因素校正的负荷，因此无需特大型UPS 

• 温度补偿蓄电池充电 Temperature Compensated Battery Charging provides prolonged battery life by regulating the charge voltage according to actual battery temperature. 

• 可升级电源容量 The modular design of the Symmetra PX allows the user to add power modules as required. Thus the user will be able to deploy UPS protection in a "pay as you grow" approach. 

可服务性 

• 自动自检 UPS可以每二周进行一次自检，以确保电池失效之前能够及时得到告警。通过软件，或者按自检按钮，此操作可以随时进行。 

• 热更换电池 The modular battery design provides ease of maintenance and reduces Mean Time To Repair. A service engineer or trained user can easily swap a battery module in a matter of minutes while the UPS remains on-line. 

• 模块水平维修 The modular fault-tolerant design ensures system availability, until service can be performed, and reduces the risk of human errors. 

• 前面维护 The front-access feature makes installation and maintenance easy and minimizes space requirements. 

易管理性 

• 内置Web/SNMP管理 Provides full UPS management via multiple open standards like Telnet, HTTP, SNMP and pager notifications. It is a full-featured, robust power management product that is certified for and integrates with all other APC management products. 

• 智能电池管理 The Symmetra PX features advanced battery monitoring and temperature-compensated battery charging. Battery data is continuously compared to preprogrammed data in the monitoring software to ensure reliable batteries. A reduction in battery capacity automatically triggers an alarm. 

• 多台UPS关断 Provides graceful, unattended shutdown for the connected servers should an extended power outage occur. 

• 智能插槽
