中国电力与UPS

Power Supply and UPS

ＵＰＳ已经成为供电系统中的重要设备，我国电力现状如何，对ＵＰＳ设备提出了哪些要求，如何正确评价一台ＵＰＳ产品的优劣等问题，都是值得研究和探讨的。

UPS has become the key equipment in the power supply systems. It is worth to study and research how the situations of the power in China is, what kind of demand to UPS we have, and how we correctly estimate a UPS.
