Looking for an easy solution to power a (say 120mm muffin) fan at a remote site.
Currently the setup is 100V from PV's that only feed a pump controller, so no batteries, no low voltage.
Obvious solutions start with a DC fan, but I've never seen one
Next is DC-DC converter with a suitable input range, but they are hard to find
Meanwell do have a range with 40~160VDC input, but finding one to buy is another story.
I'm not fussy about the output - any of the common outputs would be fine (12/24/48V), I'll find a fan to suit
My suspicion is many mains intended SMPS would work fine off DC as the first stage (after filtering) is a bridge rectifier.
Before I go down that path, is anyone using a more elegant solution?
