特色介绍
快速修复能力
传统UPS在使用中处于维护旁路模式，负载不受保护，发生电源故障或输入波动时，可能会损坏设备。同时，设备维护也需要经历一系列繁琐的程序，系统管理员需要通知厂家，制造商赶到现场进行维护关机，系统修复时间由于几个因素的不确定性。节日或节假日，维修困难时，维修人员的判断可能出错，客户现场距离一切都会花费很多时间。
EA660采用新模块热插拔技术，支持所有模块插拔。电源模块可以随时在线插拔，不需要断电操作。如果电源模块出现故障，模块将自动退出系统，系统不会受到影响。当待机模块到达时，在UPS工作时，将故障模块取出并插入新模块。然后恢复完成，没有电源关闭或转移到旁路，这实现了并行系统的在线维护。这些操作不需要专门的设备和技术。
模块化设计
EA660采用模块化设计，一个模块电源为20KVA / 16KW，系统由1-20个模块组成并联，用户可根据负载逐渐增加模块数量。在模块和机器之间使用热插拔技术，可以在线插入或取出UPS模块，从而使0s停机。
灵活冗余并行设计
EA660可以设置冗余UPS模块，并且可以设置0，当UPS可以是最大容量输出时。当负载超过冗余设计时，只要电量不超过负载模块的总容量，UPS仍然可以工作，并发出相应的警告。
扩展性
由于采用完全模块化设计，用户可根据负载选择20KVA至400KVA之间的适当容量，配置非常灵活。 UPS系统结构非常灵活。电源模块的设计理念是随时移除和更换模块，而不影响系统的运行和输出。可以根据需要扩大投资计划，使用户能够坚持业务动态发展，满足后期设备增加需求，降低采购成本。
当用户估计UPS的容量时，往往被高估或低估了
可用性
EA660并行具有优越的性能，代表了高端UPS，平均故障间隔时间MTBF是传统UPS的1.5倍，平均故障间隔时间MTBCF是传统UPS的三倍，平均修复传统UPS的MTTR时间正在下车8小时进行维护，而EA660系统维护只需5分钟，高可用性显示EA660完美的保护和使用能力，确保系统的安全和负载保护时间呈指数增长。
环保
EA660 PFC电路采用数字有源功率因数校正技术，输入电流总谐波失真（THDI）仅为3％，而输入功率因数≥0.99，大大降低了电网污染，有效降低了功率损耗。通常，负载越小，系统效率越低。数据室的UPS实际负载通常低于80％，甚至低于50％。当负载仅为15％时，EA660的效率大于90％，当负载达到50％时，效率可以达到93％以上。即使客户的负载小，系统也能实现更高的效率，为客户节省成本。ers.

Features Introduction
Quick repair capacity
Traditional UPS are in maintenance bypass mode when they are in the service, load is not under protection, if any power failure occurs, or input fluctuations, , it may cause damage to the equipment. Meanwhile , equipment maintenance also need to go through a series of cumbersome procedures, system administrators need to notify the manufacturers, manufacturers rushed to the scene for maintenance with power off, system repairing time is uncertain due to several factors. When festivals or holidays, maintenance is difficulty, maintenance staff judgment maybe wrong, the customer site distance, all will take much time.
EA660 adopt new module hot swap technology, all modules supported plugging in and out. Power modules can be inserted or removed at any time online, power off operation is not required. If a power module fails, the module will automatically exit the system, the system won't be affected. When standby module arrives, take the faulty module out and insert the new module while UPS is working. Then restoration is completed, no power off or transfer to bypass, which achieved online maintenance for parallel system. These operations do not need specialized equipment and techniques.
Modular design
EA660 takes modular design, one module power is 20KVA/16KW, system consists of 1-20 modules and connected in parallel, the user can gradually increase the number of modules depending on the load. Between the module and the machine uses hot swap technology, UPS module can be inserted or removed online, enabling 0s downtime.
Flexible redundant parallel design
EA660 can be set up redundant UPS modules, and 0 can be set, when UPS can be a maximum capacity output. When the load exceeds the redundant design, as long as the amount power does not exceed the load module's total capacity, UPS can still work, and issue corresponding warnings.
Expansibility
Due to the fully modular design, the user can choose a appropriate capacity between 20KVA to 400KVA depending on the load, the configuration is very flexible. UPS system structure is very flexible. Power module design philosophy is to remove and replace the module at any time without affecting the operation of the system and output. Investment plans can be expanded as needed, allowing users to stick with the dynamic growth of business, meeting the requirement for post-equipment increase, also reducing the cost of procurement of pre-.
When users make estimation of UPS capacity, they often overestimated or underestimated
Availability
EA660 has superior features in parallel ,that are representative of the high-end UPS, mean time between failure MTBF is 1.5 times the traditional UPS, mean time between critical failures MTBCF is three times the traditional UPS, mean time to repair MTTR of traditional UPS is down 8 hours for maintenance, while EA660 maintenance in the system only requires 5 minutes, high availability shows the EA660 perfect protection and use of capacity ,which ensure the safety of the system and the load protection time increase exponentially.
Environmental protection
EA660 PFC circuit uses digital active power factor correction technology, the input current total harmonic distortion (THDI)is only 3%, while the input power factor ≥0.99, which greatly reduces the grid pollution, effectively reduce the power loss. Typically, the smaller the load, the lower the system efficiency. UPS actual load in data room usually are below 80%, even lower than 50%. When load is only 15%, efficiency of EA660 is more than 90% .When the load reaches 50%, the efficiency can be 93% or more. Even if the customer's load is small, system can achieve higher efficiency and cost will be saved for customers.ers.ers.
