Hello,
I'm creating a black box with a few power supplies and an Ethernet connector. I want to be able to make sure when I turn power on, an indicator will turn on. I was thinking about having 3 LEDs, 1 for each power supply (48V, 5V, and 12V). I found out that my LED's "turn on" around 15mA, but they look very weak. I was going to put in a current limiting resistor for each LEDs power supply so once the power supply reaches it's proper voltage, the LEDs would turn on.
I was wondering if there is a better way to do this and if there was a way to make the LED brighter.
In all honesty, I think I'm over complicating things by trying to find the "turn on current" for the LEDs and should just put in a resistor that gives 25 mA. I just want to make sure that the power supplies are outputting the proper voltages.
Thanks,
Matt
