Re: [HamBrewers] 30 volt 29 amp PS

 

Fantastic idea. Now how can one manipulate the last smps in series for the 3.8V extra?? 73ees, Pat --- On Mon, 4/23/12, Aravind Balasubramanian (VU2ABS) <vu2abs@gmail.com> wrote: From: Aravind Balasubramanian (VU2ABS) <vu2abs@gmail.com> Subject: Re: [HamBrewers] 30 volt 29 amp PS To: HamBrewers@yahoogroups.com Cc: "Sandeep Lohia" <sandeeplohia12@gmail.com> Date: Monday, April 23, 2012, 12:58 PM Sandeep. Whats done here is all the 5 v (which usually have atleast 30A op) outputs are connected in series. Except the bottom most ps all other ps's mains earth pin is left floating. perhaps a small 5 w resistor load is also connected across each 5v / 12v output for kick starting On 4/23/2012 12:33 PM, Sandeep Lohia wrote:   It good idea to isolate earthing, but not complete information is given there, one needs to short green & black wire otherwise it won't kick start. LOL. One can also play with TL494 feedback with a variable preset. As to change 12V to 13~ EMI filter is another one!!!!! VU3SXT 73...........
