Hello all,
coming back on this unit, I know already 6 years. After changing all electrolyte's caps (I also make a little modification to put 2 little fans [one on the heat sink of the 15V regulator and the other one at the back] to get a better air flow and also display the temperature at this 15V regulator), the unit ran like a charm up to last week.
Once more a charging issue that lead to slowly discharging my batteries (on get one defect, but after some years I assuming it can be acceptable). Changing the batteries, and.... after 1 day, capacity drop to 60% without explanations....

Re: Cyber Power 2200E not switching to AC power (0V output)

Hello everyone,
I have a CyberPower Value 2200E that have the problem of charging the battery. Checking the electrolytic caps and find the same as Mladen82 : most of the 22uF/50V were defect, especially C3, C37, C39 and C41 that have about 13uF instead of 22 , ESR of 150 ohms and a Vloss of 30% ! As I was on the way, I've changed all the electrolytic caps. Then the unit work again.
I was wondering why this 4 caps were so bad. Except C3,they physically are located near the L7815CV (+15Vdc) regulator....

Hello the Badcaps Community,
I'm from Switzerland and would apologize for my English. Anyways, I've found this awesome forum while my CyberPower UPS brake down. I was looking around the Internet to find info's and schematic's and luckily found this one.
I'm in electronics for years now but not as engineer. I've been playing with early computers (4.88Mhz CPU) under DOS, but I'm not in this business branch. Now, with years, I've been facing a lot of problems due to old electrolytic caps. Main time changing them...
