Hey everyone,
I have an APC SMART Back UPS 2200 Power Supply SU2200 that I'm upgrading and replacing some parts in it.
It currently has 2 1500uF 75V 3 prong capacitors in the one area. There is room for a 3rd. I've seen several youtube videos about UPS work and adding the extra cap is ok to do, even recommended (also is adding the extra mosfets to help with the loads; which I'm also going to add).
The caps that are installed are these: http://www.ebay.com/itm/201445231125?_trksid=p2055119.m1438.l2649&ssPageName=STRK:MEBIDX:IT
I'm wondering if it would be advised to just replace the 2 (and add the 3rd) with a brand new caps. I can't find the exact replacement uF and voltage in new form. I know I can put in ones that are of higher voltage and still be ok. But would it hurt to add 1 with higher voltage to the other 2, or should I replace them to all be the same voltage?
Also, I've noticed that there are some cap that have, ie 50v 1500uF are of one size, and others larger. Why are they so different in sizes?
The main reason I'm asking about replacing with new ones is because I don't want to possibly install just one identical one, then shortly afterwards when needing to use the UPS they blow out because they are close to EoL. I'd hate to have to take it all apart after putting it into service again.
Side Note: This UPS is part of a larger project that will involve alternative energy charging methods to charge the batteries and run off the inverter for AC required devices. I got the UPS for about $60, free shipping
Thanks for the help,
Kori
