Technical characteristics of the product 1, DC cold start function: no electricity case, normal power from the battery. 2, the input voltage and frequency tolerance range is broader and better meet the electricity needs of the poor quality of the region, extending battery life. 3, strong overload capacity overload can be avoided for the moment transferred to bypass, once mains voltage is high, resulting in load damage. 4, with the mountain special monitoring software, do the intelligent power management. 5, three-phase power supply input terminal, avoid phase unbalance, affecting any of the other devices share the same power. The output of a single-phase power supply, easy to load distribution. 6, CPU control, the relative increase the amount of information, simplifying the UPS circuit design, to accelerate the reaction control, reduce UPS failure rate. 7, may at any time hot backup, to improve the reliability of UPS. 8, you can manually detect the battery pack is normal, to avoid once power failure, battery failure, causing power outages caused by the soft, hardware damage. While the online service, that is not the fault interrupt output and UPS testing. , The actual available capacity battery and the following factors related to: ① battery discharge current size ② ③ battery ambient temperature storage battery, the length of time for use ④ load characteristics (resistive, inductive, capacitive) and size only in consideration of the above After the factors before determining the proper selection and use of the battery capacity and the battery for the ratio of nominal capacity. UPS backup battery capacity determines the long delay important factor is the load size, type and characteristics
