摘要
不间断电源UPS的用户设备,都是清一色的计算机及其外设,这些设备都采用了开关稳压电源,不一定需要交流供电,而直流供电免除了谐波干扰,更增加了数据处理、传输的安全性和可靠性。无逆变器不间断电源UPSWI免除传统UPS中的逆变器,对用户设备实现直流供电,在保留所有外部特征的同时,各项技术性能都大大超过,而成本、体积、重量、功耗均为相同功率传统UPS的十分之一。
The user equipment of UPS is all the computers and its external devices in which the switch power supply has been more widely adopted.It is not necessary to run the user equipment with AC,and to run with DC instead of AC can get rid of the harmonic interference and increase safety and stability of processing and transferring of data.The UPS Without Inverter(UPSWI)get rid of inverter in conventional UPS and run the user equipment with DC,holding all the external performance,and every technical parameters are much better than of the old one,its cost,weight,volume and consumption decrease to 10% of conventional UPS of same power.
