Re: APC UPS units - troubleshooting
Sounds bad and many companies being anti-repair :\
63v 22uF should be ok?
What if I tried LE first to see if there is any feedback and how do you detect feedback, can it damage equipment connected to ups?...

Re: APC UPS units - troubleshooting
How can you see if there is feedback?
The only other option on display is this one but 63v? and the original is maybe 16v?
KMG (EKMG630ELL220ME11D)
btw this farnell seems to have something with tax and can only send from uk so there is probably customs ...

Re: APC UPS units - troubleshooting
Dunno it was 5eu postage for a couple of caps Did check the "Where can I buy replacement capacitors" thread and checked digi 30eu+ postage and my country "si" is not even listed in the thread. Maybe need to check postage on all those and if they send here? edit: ok its 7eu on farnell do they have anything good?
I see ur looking at [URL="https://eu.mouser.com/datasheet/2/315/ABA0000C1209-1289053.pdf"]Impedance*2(Ω)[/URL]?

Re: APC UPS units - troubleshooting
That is the only recommended brand that is on conrad.com which doesnt cost an arm and leg in shipping But maybe theres some other that i didnt find.
Im out of my depth here but tried to calculate esr according to this equation.

Both of those caps linked give this datasheet NHG-a.

Re: APC UPS units - troubleshooting
Damn just received them today. So I guess low-esr is low impedance?

How bout this one, it says general purpose, 50v?
Or this one same line, cant even see the difference.

Re: APC UPS units - troubleshooting
Thanks. Luckily they were on this conrad shop and ordered a bunch just now. Hopefully can coerce a friend with proper soldering equipment to help me so that I dont cook everything with my noname 8eu iron

Re: APC UPS units - troubleshooting
Or are these ones ok for this unit? Lead spacing, 35v? Found that originals are likely 16v, cant open the unit yet. 5eu postage and caps 0.2eu it seems.

Re: APC UPS units - troubleshooting
Hi
Got a SUA1500I bought oct.2009 and its still chugging along on its third battery pack, mostly in cold environment except for like 3 months in a year. But I see these mentions everywhere about the 5 22uF caps and im kinda worried.
What should the minimum voltage of the cap be?
Are these SPK caps any good? Didnt find them in good or bad caps threads with search. Store kinda near me carries them I think.
