Looking for, how to build, locate, create a solution
The problem:
I have many systems that need 12vdc at 6a.
When the PS fails, someone needs to drive to this locate and swap out the PS, this could take a day or more
The idea:
Monitoring the PS(A) 12vdc out. If the 12v goes beyond threshold
..the relay turns off power to PS(A) turns on PS(B)
Maybe a timer, wait 5 minutes before switching to PS(B)
USB sends a "1" ( or stops sending a '0')
Problem, when PS(A) fails, there is no power, other than 110vac
Use a battery or capacitor to power the circuit ?
When PS(B) is powered, 12v and/or USB 5v is available
The system will notify that PC(A) not working....be replaced when convenience.
Thanks
