Off line UPS System

Again the two  switches  are used in this  type of ups  as online  ups. The difference  is that  here  the main  static  switch  remains normally  ON and UPS  static  switch  remains  normally OFF.

Here the load  is directly connected to the  main supply  through  main static  switch. Under the condition of power  failure, main static switch   operates to disconnect the  mains from  the load and then ups  static  switch  becomes ON to  connect the load  batter by bank through  circuit. Battery bank  suppliers  the power  to the load.
