UPS in Chinese means "uninterruptible power supply" is the abbreviation of the English "Uninterruptible Power Supply", which can protect the computer system to enable users to save emergency continue to work for a period of time after a power outage, so you do not affect the work or lost due to power outage data. Role of uninterruptible power supply: emergency use, to prevent a sudden power failure and affect the normal work and cause damage to the computer; Second, is the elimination of the surge on the mains, instant high voltage, instantaneous low voltage wire noise and frequency offset shift and other "power pollution, improve the quality of power supply for the computer system to provide high-quality power supply products: US11T series of small, single-phase UPS provides excellent electrical performance, friendly and intuitive user interface, the protection of your device in one step, to meet your high reliability and high availability of comprehensive requirements; compact, stylish design, easy to match your equipment environment; meet the long delay models provided poor quality of supply to demand and management of the area of ??the large capacity battery. The product features high reliability, innovative streamlined structure design, especially for IT class load (office terminal server, memory, VoIP, broadband access ......) ensure that the load safe and reliable operation. ■ excellent quality of power supply performance surge suppression, can absorb the power grid pollution output pure sine wave. ■ friendly interface with self-diagnostic function, combined with more use of voice alarm LED indicator, easy access to state information, real-time display of battery capacity and load capacity. ■ easy to use UPS to provide input overcurrent protection and overload protection, the protection of the critical moment easily. ■ more comprehensive protection functions US11T in not only protect your computer, but also for computer peripherals to provide Internet access surge protection function. ■ extend the battery pack life ultra-wide input voltage / frequency range effectively reduce battery discharge probability; super-charging capability effectively shorten the battery recharge time, prolonging life. US11T-0020 standard machine built-in battery 2000VA/1600W That can be with a load 1600W equipment. If your device is more than 1600W then they would have the choice of a large number of power UPS. Probably 1600W backup time: 5 minutes. 800W time of 15 minutes, an external battery pack for longer delay time, please use long-acting machine. Installation Notes: 1, (1) to place the UPS area must be well ventilated and away from the water, combustible gases and corrosive. If (2) should not be side inlet hole should keep the bottom of the front panel, the rear cover the fan out of the wind unobstructed hole (ensure that the distance between the UPS cabinet and other objects around greater than 0.5 m) (3) machine at low temperatures disassembly use, there may be water droplets suspected knot phenomenon, we must wait for the machine inside and outside is completely dry before installation, otherwise there is a risk of electric shock. 2, (1) the machine continued to be installed by professionals, in accordance with local electrical codes for wiring as follows. What is the difference between the lead plane and standard machine: A: The standard machine as the standard built-in battery machine, without external battery. A: The long-acting machine need an external battery will have preparation time, internal machine is no battery backup time is based on the configuration of your equipment needs backup time, this one is called long-acting machine.
