Hi
Ive been looking at small PS modules around on the web via different manufacturers but what I would really like is a way to have a module that delivers (customizable/pre-settable) fixed voltage in the range 3-20V, 500ma and a efficiency of at least 90% +, should also be of low complexity if possible. Primary input in the range 120-230V
Are there any off-the-shelf solutions that can be looked into for this where I can avoid custom-made flyback transformers etc ?
Thanks and regards
