Hi. I'm new here, be gentle
I have a circuit where I need a 12VDC current limited LED to light up when a voltage between 150 to 300VDC (2-4 A) turns on.
I have a 12VDC power source that I could use to power the LED, but I basically need a good way to control it. I thought about using a relay that supports voltages up to around 300VDC on the control signal and a low current on the switched signal but I can't seem to find any that matches.
Oh, and all of these things are external mounted devices.. No PCB components.
Does anyone have any good ideas on how to do this?
Thanks,
Tomas
