DSM is a high frequency, on-line double-conversion uninterruptible power supply. 0.9 output PF makes better available for load. In the same time, 6 system parallel is available, which meets the requirements of users’ demand. DSM design and high control technology provides better protection and higher reliability on load. The UPS has been designed to protect critical information and telecommunications systems, networks, services and processes whose operation could be disrupted by poor power quality and/or breaks in their mains power supply.
    1.Zero Impact Source
    Low input current distortion - less than 3%, high input power factor 0.99; 
    Delayed start-up protects its power supply sources (mains or generator) from any harmonics and reactive power generated by the loads it is powering. 
    2.Battery Care System
    Two voltage level recharge meeting the IU characteristic; 
    Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient
    Extensive back-up time options using battery extension cabinets
    Battery test: to detect performance degradation and predict battery failure. 
    Cycle recharge function. Battery could be maintenance as battery manufacturer’s requirement, in order to extend the life of battery. 
    “Trial charging” recharging function, in order to avoid voltage balance after changing battery. 
    3.Extension inverter design capacity, which give guarantee on 115% load (PF0.8) long hours.
    4.Without any reduction in active power, from 0.9 inductive load to 0.9 capacitive load
    5.High efficiency design, more than 95%(online mode)
    6.DSP microprocessor technology give guarantee to static characteristics and dynamic characteristics in any operation situation.
    7.Simple and convenient separation bypass
    8.Variety of intelligent communication. User could remote monitor and control, easy management, and it realizes the unattended operation.
    9.8 languages are available: Italian, English, French, German, Spanish, polish, Chinese, Russian.
    Finance, Transportation, Broadcast & TV network, Data processing center, HealthCare, Communication, E-Business, etc.
