随着信息产业的发展,UPS电源已经成为计算机系统外部设备中不可缺少的重要组成部分。对于已经购买了UPS电源的广大用户,在经历了一个长期的实际运行以后,对UPS逐渐加深了解,正确掌握了运行规律和操作方法,为他们下一次选购UPS电源,积累了宝贵的经验和教训。然而对于那些第一次参加选型的新用户来说,面对着日益竞争激烈的UPS市场,面对商家闪烁其词的产品广告,往往感到困惑而难以决断。 事实上UPS作为计算机系统的供电保障,最重要的是可靠性,而可靠性又是一个产品的综合性能指标的体现,绝不像某些人讲的那样,用一个“平均无故障时间”(Mean Time Between Failures,简称MTBF)指标就可以完全决定。 诚然MTBF是衡量UPS可靠性的重要指标之
With the development of information industry, UPS power supply has become an indispensable and important part in the external equipment of computer system. For the majority of users who have already purchased the UPS power supply, after going through a long-term actual operation, they gradually deepen their understanding of the UPS and correctly understand the operation rules and operation methods. They have accumulated valuable experience for their next purchase of UPS power supplies lesson. However, for those first time to participate in the selection of new users, in the face of the increasingly competitive UPS market, the face of business advertising flashing products are often confused and difficult to determine. In fact, UPS as the power supply of computer system protection, the most important is reliability, and reliability is a product of the overall performance indicators, not as some people say, with an “MTBF” ( Mean Time Between Failures, referred to as MTBF) indicators can be completely determined. It is true that MTBF is an important indicator of UPS reliability
