I want to use some cheap LED strings for a landscape application. My current landscape xfmr puts out 12VAC (actually near 14VAC to be accurate). Does anyone know of a small, 12AC to 12DC converter, sealed so outdoor use wouldn't be an issue?
AC buckpuck?
32VDC is the maximum DC input voltage. As stated on the link:So, if I read that right, I can put 12VAC into it, and can drive a pile of LEDs. However, the output voltage claims 32VDC, won't that fry a string that usually operates at 12VDC?
Yes, that's definitely true. If the input is 5VDC then you can only run 1 LED. If it's 32 VDC then you can probably run 9 LEDs, possibly even 10 if they have a low Vf.But it is a buck driver so the input voltage HAS to be more than the output voltage.
I haven't been through the AC datasheet but the DC needs about 1-2V overhead.
So for the OP this would mean 14V would drive what 12V is driving now.... assuming the current setup is just LEDs (cheap LED strings... could be a few things), if its a string with a built in driver who know if it will work or not.
