Hi guys.
Okay, I'm trying to find a relay for my project. But all the choices, therminologies, and specs really confuse me. So maybe I can explain what I need and you guys can point me to the right relay to get?
So I have a 12V circuit, and two 110V AC circuits. One is from the grid (15A), and the other is from a PSU (3A). And the load is a 1A LED monitor.
Whenever the 12V circuit is closed, I would like the load to take power from the grid. And when the 12V circuit is opened, I would like the load to to take power from the PSU.
What panel mounted relay should I buy?
And how do I handle the ground wire? Can I have the load connected to ground on both the PSU and grid at the same time? Or should I have a relay that switches the ground wire too?
And if it matters, here is the PSU I'll be using:
