The Uninterruptible Power Supply gives a clean, continuous, stabilised AC Sine Wave Output inspite of variations in the Input or the Load.  The  defects  of  blackouts  and  brownouts  usually present in the  Main  Supply  is  thus  eliminated. The UPS mainly consists of a Float Charger, Inverter and the necessary protection circuits.

The functions of the  Float Charger is to charge the Batteries and simultaneously supply power to the  Inverter.  The  Inverter  converts  DC  to  AC  to  get  a  stabilised  voltage  at  constant frequency.  LC filter components are perfectly matched to get a clean, distortion free Sine Wave Output.  The control circuits maintain the  Charger and the  Inverter voltage at the particular level. Instantaneous status of the Mains, Battery and Load are indicated on the front panel. Electronic Protection circuits  are provided to implement proper and efficient functioning of the Inverter and Charger.
