I would like to use a system switches the power from the Main Power Supply to the Battery Power AGM whenever 'Main Power Supply' is absent.


I will try to explain what I want..

The circuit should accepts 2 input DC voltages , the first input voltage called "MAIN_SUPPLY" 24 V, the current is 25A which will be the "ALWAYS ON" input that may vary between 22VDC to 25VDC. If the main supply goes OFF then my output LOAD should switch to the secondary input which will be treated as batteries (AS BACKUP) .. Battery Voltage may change from 20V to 28V (Due to the charging). the reason is to run a dc motor 600 W without interruption all the time

I really appreciate your help.
Regards,
