This Dc Ups can power any electronic device from 12v to 35 v , and power output is upto 150 watt . With addition of an ac inverter you can power any Ac appliance too!

Programmble output,battery cut off,
automatic battery management circuit
Dc - Ac Input,Dc - Ac Output (With dc to ac inverter)

This Uninterupted Power Supply can be instead of generator or inverter to any DC or Ac Powered Appliances Just need Dc to Ac converter for 230v or 120v ac volts . I provided explianation for each of the pat of the circuit diagram in details.

Battery i used is 12v 7 Ah , Exide lead acid , and casing is reused from SMPS ( switch mode power supply) from computer power supply.
#Circuits Used
Voltage divider - For battery voltage sensing
dc to dc converter
