Posted by cobracam88 on 6/28/2007, 11:36 am, in reply to "Re: ARIES 50 AMP POWER SUPPLY SCHEMATIC" OK - sorry about the useless info +___+. If you want a 'tight regulation' then use a 723 - here is a schematic: http://www.rason.org/Projects/powsupply/powsupply.htm Or if you want a simple circuit, for fair regulation then use a 7815 regulator going to a TIP 41 (or equiv) going to the 2n5885 pass transistors (also use appropriate bypass caps), and you have a fairly stable 13.8 v. regards

: Hi,
: Thanks for your help but the pass
: transistors are 2n5885's wich cary more amps
: than a 2n3055. Also the parts in question
: are smaller transistors on the control
: circuit board. I may just have to Build a
: new control circuit. Thanks again!

: I do not know what transistors are used on
: this power supply - but most power supplies
: use 2N3055 NPN TO-3 transistors for the pass
: transistors. (Even if they are not the
: 2n3055's, as cheap as they are, get enough
: to replace all of the pass transistors, and
: if necessary simply re-wire it to use these;
: esp since they ARE the most common *__*)

: HI,
: Looking for a schematic of an Aries
: A-PS50M. Or some one can tell me what the
: part numbers for Q1,Q2,Q3. My power supply
: smoked and burnt those parts so bad I can't
: read the numbers. A pass transistor shorted
: out! Thanks Danny
