Introduction
General (UPS uninterrupted power supply)
UPS   power  supply  belongs to uninterrupted  power supply  that  has  high  efficiency , small  volume,  nice  appearance,  advanced  andreliable  performance specially designed for microcomputer system and precise electronic instrument.  When the commercial power is normal, it  outputs voltage stabilized AC power supply;  when the power fails or the voltage is too low  or too high, the inverter powered by battery outputs AC to load in 10 ms . During  battery  supplying  power,  if the commercial  power resumes, the inverter  in the  machine will stop  inverting immediately and  the commercial power restore into use; the battery is charging at the same time.
 Features (UPSuninterrupted power supply)
      UPS  series  is  designed  based  on  UPS-H  series with the improvement in the inverting  transition  time . So,  it  is  more  
economical  and  more suitable  for computers in the family and office.
