It is our honor to introduce ourselves as an exporter in China. We are specializing in manufacturing PC power supply, industrial power supply and other computer hardware. Our USPS (Uninterrupted Switching Power Supply) is a new kind of switching power comprise with PC power supply and UPS (Uninterrupted Power Supply). It enables computer to have UPS function. It is more easy to use and more comfortable. It ends the history that many people use external UPS for their computer systems to avoid power cut off. This uninterruptible switching power supply has two sets output voltage and two inside batteries. Meanwhile, USPS is the basal unit of protection power supply project and has the energy renewing with the internal and overseas patent. It can economize 5-20% energy than traditional UPS, as well as reducing hardware investment and running cost. USPS reaches international standard and most of the OEM&ODM products, sustaining the display and printer working environment. If you are interested in it, pls kindly let us know. We'd be pleased to send you more information about it. Many thanks!
