UPS作为一款不能使用变压器在线式维谛UPS，LiebertAPM具备领域*理想的高效率，根据添加内部结构FlexPower™组芯，可以实现随需扩充。这种情况芯可以使设备在一个网络机柜内以15kW的增加量扩充或多余至45或90kW。
FlexPower组芯在一个普通组内融合了分布式智能和可扩展性的开关电源，适用配备彻底多余的电源装置自动控制系统，可以随需扩充达到受法律保护负荷容量。当开关电源要求发生变化时，数据中心管理工作人员无需提升全面的占地总面积便能方便地提升容积。此方法完成了UPS的随需配备，优化了能耗等级，减少了开关电源成本费。
维谛网络能源北美开关电源工程项目**副总裁CharlesO’Donnell说：“我们不难发现，现如今的数据中心必须免变压器UPS系统软件，LiebertAPM根据能源之星的认证，说明其技术性可以促进全部经营规模大数据中心整体效能提升。”
做为电气设备能耗等级改进方案的一部分，国外国家环境保护局（EPA）于今年稍早对于输出功率为1500瓦之上（包含1500瓦）的商品建立了UPS能源之星方案。为了实现能源之星验证，LiebertAPM接受EPA承认的UPS**认证的检测。该验证全过程根据均值开关电源、效率高效率转变对开关电源恒稳定进行检测。达到EPA标准的UPS商品会比同行业降低35%的能源消耗。
Advantages of Weidi APM Modular UPS
As an online Emerson UPS that does not use transformers, theViti APM modular UPS has the industry's best efficiency through theaddition of internal FlexPower ™ Core assembly, capable ofon-demand expansion. This core assembly can enable the system toexpand or redundancy to 45 or 90kW in increments of 15kW within asingle cabinet.
The FlexPower core integrates distributed intelligence andscalable power supply in a regular group, supporting theconfiguration of fully redundant power and control systems, and canbe expanded on demand to meet the capacity of protected loads. Whenpower requirements change, data center managers can easily increasecapacity without increasing the system's footprint. This methodachieves on-demand configuration of UPS, improves energyefficiency, and reduces power costs.
Charles O'Donnell, vice president of power engineering in NorthAmerica of Emerson Network Energy, said, "We found that today'sdata centers need transformer free UPS systems. Liebert APM passedthe certification of Energy Star, which shows that this technologycan promote the overall efficiency of data centers of allsizes."
As part of the energy efficiency improvement plan for electricpower equipment, the National Environmental Protection Agency (EPA)formulated the UPS Energy Star Plan earlier this year for productswith power above 1500 watts (including 1500 watts). In order tomeet the Energy Star certification, Liebert APM has been tested bythe UPS certification authority recognized by EPA. Thiscertification process is based on testing the constant state of thepower supply based on average power supply, efficiency, andefficiency changes. UPS products that meet EPA requirements reduceenergy consumption by 35% compared to similar products.
