ENERMAX Liberty ELT500AWT

Re: ENERMAX Liberty ELT500AWT

Yeah, could be, I asked Panasonic for PN of possible 3300 uF/16 V D10 too. I think the NCCs win it for me, at least 6,3 V wise.

I just asked at Digi-Key whether they can get some quotes for those 6,3V versions…

Re: ENERMAX Liberty ELT500AWT

I've been using the 10mm 16V 2200uF and 6.3V 3300uF Panasonic FK for a while now.

UCC also has these, but they're custom sizes and I've never seen them for sale through any trusted distributor.

The Panasonic FK are stocked in the UK warehouse, and the US warehouse gets a small quantity shipped every few months, so I don't have to pay anything extra for them which is nice.

Those two new series KYA and LZA are unremarkable. FK is better rated than both of them.

Re: ENERMAX Liberty ELT500AWT

I have been using 3300 uF everywhere and often 2200 uF is not enough.

That's why I am trying to find the PN and get some distributor order them I don't see why the manufacturer would make them for PSU makers and not for distributor?

Re: ENERMAX Liberty ELT500AWT

16v 3300uF - I don't think there were any custom 10mm sizes ever made from any of the Jap manufacturers... What you should do is bug Digikey (Because Digikey seems to carry the most UCC stock) for a custom size KZH series for that cap.

Re: ENERMAX Liberty ELT500AWT

I asked for the NCC KYA and Pan FK.

Joe had them supposedly made as Samxon RS. Now this is not Jap company, but I'd dare to say one of the -very- few non-japan quality makers.

I am sure others exist as well. I can't tell where but I am sure I have seen some 3300uF cap even from quality maker in some PSUs. If you'll happen to know such PSU and get pics, I can show them they're lying and such caps exist from them and we have pics

Re: ENERMAX Liberty ELT500AWT

Why do you say supposedly for the RS? I've ordered these before from Joe and in fact I'm using them right now in my PSU.

Why not just pay the $8 for these:

Re: ENERMAX Liberty ELT500AWT

Cause he said he had them on special order. Who knows but him? Maybe Man Yue sold 95000 of them to some company and he took 5000?

That guy got only like 30 pcs left, that won't save me for more than a couple weeks, not mentioning the price would be insane per piece.

Re: ENERMAX Liberty ELT500AWT

But I thought you only needed 2 pieces for this PSU?
Only other manufacturer besides Teapo (I think the Teapo SC is pretty reliable at the higher values) is PCE TUL series:

Do I seem like Mad Professor? I am just parasiting on his thread

These are bad caps as well as Teapo (just recently used some of my RS to replace bloated TULs, TURs or whatever). Any other crap manufacturer seems to be making something in this can with this capacity, but it is obviously not what we want

Re: ENERMAX Liberty ELT500AWT

SO I seem to have made an error, I have two different series, KM and FM caps. Since I have the KM datasheet now I need FM datasheet and no not panny sheets, I need the CTC one, or if someone knows off hand what I should replace FM caps with?

Any one know if I can use UCC LZA caps for the 3300 16v caps which uses a KM and FM cap before and after the pi coil.

Re: ENERMAX Liberty ELT500AWT

That LZA ripple/ESR seems to be OK, but that diameter

Re: ENERMAX Liberty ELT500AWT

You can find all Panasonic datasheets (and other manufacturers/brands) here:

ftp://helpedia.com/pub/temp/datashee...ors/Panasonic/

It's long overdue for some organizing at that url, but it should do for now. Working on getting updated catalogues for everything there, but doing it in my free time. Copy it all if you want, they're not secret or anything like that.

LZA seems acceptable for a power supply, what seems to be lacking is high ripple capability.. only 2350mA compared to 3500+ at FM/FR series or other manufacturers. But they're also smaller, at only 25mm or so in height, compared to 35mm for Panasonic.

I'm not sure how much this lower ripple capability is a factor in selecting the capacitor, if the power supply is well designed it the capacitor may never see this much ripple.

Re: ENERMAX Liberty ELT500AWT

Samxon RS have similar ESR and I find them pretty much suitabe into every PSU, hardly ever made problems for me. On the other side, there are documented cases of caps with slightly lower ESR than of FM/FR making supply oscillate. For that reason and in regards of „better safe than sorry“, I never use them personally…

Re: ENERMAX Liberty ELT500AWT

either I can't seem to write in a way that people can understand me or people around me just don't read or are just fucking stupid.

CTC FM series cap.

*RAGE!*

FUCK IT! PANNY FR's ARE GOING THE FUCK IN! IF I HAVE TO RUN WIRE TO THE OTHER SIDE OF THE BOARD, SOLDER AND HEAT SHRINK THAT BITCH TO MAKE IT WORK! I WILL! FUCK THIS SHIT!

IT'S SO HARD TO GET A GOD DAMN STRAIGHT ANSWER AROUND HERE!

I JUST WANT MY PSU AND THE OTHER TWO PSU's AND THE HATACHI TV FIXED, AND I'M SORRY, IF I'M SUCH A FUCKING NOOB AROUND HERE. I'M TRYING AND IF PEOPLE JUST DON'T TELL ME WHAT I NEED TO DO OR WHERE TO LOOK, HOW AM I SUPPOSE TO FIX ANYTHING!?!?!?! I MIGHT AS WELL GO TO EE SCHOOL!

FUCK IT!

Re: ENERMAX Liberty ELT500AWT

Hey man, calm down.

Answering to the best of my ability. There's no exact answer.

You asked

"Any one know if I can use UCC LZA caps for the 3300 16v caps which uses a KM and FM cap before and after the pi coil."

and I told you it was, imho, acceptable to be used. But since I don't have actual experience with this power supply and its design, I had reservations which I explained.

The ESR is reasonable for capacitors for power supplies, the ripple might be too low but I don't know how high is the ripple in regular use.
The capacitors in the power supply may only be subjected to 500-1000 mA of ripple, in which case it won't matter that LZA only has 2350mA ripple compared to the FM's 3500mA+.

Use LZA, use FM, use FR ... they'll all work, but nobody can tell you they'll work perfectly unless they personally repaired that power supply.

Re: ENERMAX Liberty ELT500AWT

When there's only 1 or 2 series of caps which will fit (like in this case), then I just disregard the specs (as long as they aren't GP caps). The Panny FR caps will work just fine. The ripple may be a bit higher than when the PSU was new, but they will work fine. Go ahead and use them if they fit.

Re: ENERMAX Liberty ELT500AWT

Hi guys,

Sorry for interupting caps thread , I need help with yet another one Enermax ELT620AWT.

PSU has standby 5V, can be turned on without load(bridging green and black) but it wan't turn on when there is load ( attached to motherboard alone )

When it's on all voltages are ok, 3.3V, 5V and 12V.

What was done on it:
- Replaced all the caps on rail exits
- Replaced small caps 2.2uF and 10uF on the small board on the side ( where is UCC3817 and LM393N )
- Replaced SP223 IC chip
- Replaced optocouplers
- Checked most of the diodes, transistors, don't have any obvious shorts or similar problems

What to check next ?

Did someone have similar problems with this units ?

I have 2 of them and both are acting the same...

[Behemot]

Re: ENERMAX Liberty ELT500AWT

Did you also replace caps on +5 V SB rail? I got similar problems with these bloated. Fortrons also do that.

[bgaservis]

Re: ENERMAX Liberty ELT500AWT

Do you think the ones that are rated 10v 1000uF and 10v 1500uF ( bottom left ) ?

[Behemot]

Re: ENERMAX Liberty ELT500AWT

Yeah somewhere around there. Should be for +5 V SB and -12 IIRC in there.
