UPS发展现状UPS(Uninterruptible Power System),称之为不间断供电电源,在其发展初期,仪被视为一种备用电源。后来,逐渐发展成为一种具备稳压、稳频、滤波、抗电磁和射频干扰、防电压浪涌等功能的电力安全保护系统。目前,UPS的制造技术经过长时间的发展,较为成熟,国内外各大UPS制造厂商均可以提供如下三种主流的UPS机型:1)在线式(Online)UPS供电系统,这种在线式UPS供电系统可以提供了十分理想的输出性能。它
UPS development status UPS (Uninterruptible Power System), called uninterruptible power supply, in its early stages, the instrument is considered a backup power supply. Later, it gradually developed into a power security system with functions of regulation, frequency stabilization, filtering, anti-electromagnetic and radio frequency interference, voltage surge prevention and the like. At present, the manufacturing technology of UPS is relatively mature after a long period of development. The major UPS manufacturers both at home and abroad can provide the following three mainstream UPS models: 1) On-line UPS power supply system, which is an on-line UPS Power supply system can provide a very good output performance. it
