wink Posted October 26, 2011 Report Share Posted October 26, 2011 ECQF6392JZ3: 0.0039uF 630V Polypropylene Film Capacitor (Radial Leads) Made By: PANASONIC Part Number: ECQF6392JZ3 $0.5000 Seeing as Mouser has only 1 3900pF 630V multi layer ceramic cap left, would this be a viable substitute for the TDK FK20C0G2J392J in the power Supply?

deepak Posted October 27, 2011 Report Share Posted October 27, 2011 Is there interest in a group buy for KGSSHV transformers? I believe the last time one was organized from Sumr () the only thing that needed to be done was get the specs to Richard, then everyone was able to pay separately and got them shipped straight from Richard to themself Quote Link to comment Share on other sites More sharing options...
HDen Posted October 27, 2011 Report Share Posted October 27, 2011 I'd be interested. Quote Link to comment Share on other sites More sharing options...

deepak Posted October 27, 2011 Report Share Posted October 27, 2011 I sent him an email, I will start a new thread if it's possible. I emailed him the specs Horio posted in post #1012, but mentioned the 450v option as well. Quote Link to comment Share on other sites More sharing options...
cobra_kai Posted October 27, 2011 Report Share Posted October 27, 2011 I'd take one Quote Link to comment Share on other sites More sharing options...
spritzer Posted October 27, 2011 Report Share Posted October 27, 2011 I'd be in only if SumR wasn't already making my transformers... Quote Link to comment Share on other sites More sharing options...
digger945 Posted October 27, 2011 Report Share Posted October 27, 2011 Same. Primrose is making T2 'roids for me now. I'de go in for one if it meant a discount for everyone else. Quote Link to comment Share on other sites More sharing options...
deepak Posted October 27, 2011 Report Share Posted October 27, 2011 I heard back from Richard: "A/ you have shown 100VA as total power below? The transformer, given your current capacity is 390VA. Can you please clarify. B/ We can make slightly different low voltage windings, but I would like to know what they are before commencement of any production. C/ Do all your members require only a 117V primary?" I forgot to mention the part number in the email, but just sent him that. I'll look through the thread for the 450v specs. I also requested he ship these to individual people like last time, I think it will work out cheaper and easier this way. For those of you who are planning to build the 500V output version of the KGSSHV, here is the transformer I worked out with SumR. Part #: RC0100 049 1 Specifications:100VA / 117V primary2 x 450V (@100mA output ea) secondaries making these 150 mA per Kerry's recommendation1 x 30VCT (15V-0-15V) 10VA secondaryCore bandStatic shields I believe you should be able to email SumR with this part number, and he'll know exactly what you are after. Either way, I'd still confirm the specifications with SumR just to be safe. Cost came out to $91/ea for my order. I purchased (4) transformers, so I am not sure if I got a bit of a discount. They said it would take about 2 weeks to fabricate, and probably a week or so to ship. If you are planning to do the standard 450V build, you'll probably want to modify/lower the HV secondaries a bit so the PS will run a bit cooler. Maybe KG or someone else chime in, and give you the target secondary voltage under 100mA load. Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted October 27, 2011 Author Report Share Posted October 27, 2011 390VA should be 150VA 450v x .150 amp is 67 watts x 2 is about 140 watts plus 10 watts of low voltage. Quote Link to comment Share on other sites More sharing options...
Pars Posted October 27, 2011 Report Share Posted October 27, 2011 Looks like he assumed 450v x .1 amp = 45W x 2 = 90W + 30V * 10A = 300W = 390VA Quote Link to comment Share on other sites More sharing options...
kevin gilmore Posted October 27, 2011 Author Report Share Posted October 27, 2011 That makes sense. Wrong, but makes sense. 1 Quote Link to comment Share on other sites More sharing options...
Kerry Posted October 27, 2011 Report Share Posted October 27, 2011 Yeah... 10A is a bit overkill for the LV Quote Link to comment Share on other sites More sharing options...
Horio Posted October 27, 2011 Report Share Posted October 27, 2011 I'll look through the thread for the 450v specs. I believe the only difference for the standard build (450V output), is the two HV secondary windings want to be 420Vdc@150mA. Quote Link to comment Share on other sites More sharing options...
