    Excellent performance, simple appearance, perseverance, online double transformation design, DSP digital technology, illustrating the integration of cutting-edge technology and traditional products. It is the preferred product for small and medium-sized servers and computer rooms.
    
    
    
    
      ◆ The application of advanced DSP digital control technology makes the performance of UPS more stable and the quality more superior.
    

      ◆ The load power factor is 0.8, which is suitable for the development trend of electrical equipment and has stronger load capacity.
    

      ◆ Active input power factor correction (PFC), input power factor up to 0.98 or more
    

    ◆ Wide input voltage frequency range,
    

    extremely wide input voltage and frequency range, adapt to remote areas with very harsh power environment.  
    

      ◆ Can be matched with generator.
    

      ◆ Cold start function.
    

      ◆ Zero switching, effectively ensuring the safety and reliability of load operation.
    

      ◆ Powerful monitoring, standard RS232 communication interface and intelligent slot, expandable SNMP card, RS485, AS400 card, EMD environmental monitor, etc.
