[NJARC] Switching supplies

[Nick Senker]

Edward; All Electronics (www.allelectronics.com) has a large selection of switching power supplies (and other electronic items),  It is not clear what you are looking for - is it a battery eliminator? AES (www.tubesandmore.com) has a battery eliminator kit with multiple DC outputs which I am looking into.  It is discussed in detail by Doug Criner at www.enginova.com/batt_elim.htm and at Nostalgia Air under Forums.  There are many other designs on the web, just google 'battery eliminators'

>Hello all,I hope everyone has enjoyed their holiday off. And to all who have served, thank you. And to the men and women who died to give me this day off and enjoy it in the greatest nation on earth, I wish I could thank them.Anyway, I have a question. Does anyone have a neat little schematic for a switching power supply replacement for a battery? I see many "portables" had 90 V or 100V batteries and I figure they may have drawn up to 400 milliamps. I figure most are around a few hundred.milliamps.  Anyway I know  you get the point.  But if anyone has or knows of a switching design that is compact, efficient,   and cost effective and would like to share it I sure would appreciate it.Edward
