Hi.

Can someone please recommend a commercial SMPS for this project (not hypex they too expensive for me)

OR..Can we start looking at developing an open SMPS for next year 2018, I feel there was good moment on this projec,t but to complete it, we need a power supply project to compliment the work, im stuck with heavy expensive transformer options which I cannot afford. How about a +/- 52v 8A model?

I have access for a small R&D budget and new epcos N87 cores and various some filter parts for the input for a offline SMPS, my issue is the magnetics and winding I will need help when the time comes for now its up for discussion.
