UPS uninterruptible power supply has the functions of voltage stabilization, frequency stabilization, filtering, anti electromagnetic and RF interference, anti voltage surge, etc. when the mains power is abnormal or interrupted, ups will immediately supply the electric energy of the battery in the machine to the data center through inverter conversion, so as to maintain the normal operation of the data center and protect the software and hardware of the computer from loss. At present, Huawei&＃39;s ups is used by our company, and its stability is several grades higher than that of the previous brand. We are very satisfied. Moreover, Huawei&＃39;s share of high-power UPS above 200KVA in China has always been the first, which has strengthened our determination to cooperate with Huawei all the time.
