  • Page 4: Chapterⅰ Product Description

    ChapterⅠ Product description 1.1 Synopsis The present specification defines the technical characteristics of the UPS, a device which supplies clean and stable energy to the connected load. In case of mains failure, the UPS can supply power from battery. The combination of isolated transformer, the high frequency double-converter structure and advanced DSP control makes the UPS completely immune to the disturbances of mains input and provide high-quality sine wave power.
