CyberPower 2200E not switching to AC power (0V output)

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

I wish I'd found this forum and thread at least 24 hours ago!

Working on two 2200E units with identical problems - blown components (IC, resistors, caps, fuse).

Will now also check all caps after reading this thread.

I need help identifying the blown components as they have basically disintegrated!

Anyone able to help with a service manual and/or circuit diagram with component listings?

Thanks in advance.

Edit: Just checked the posted pics of the PCB which has helped to identify some of the components, so my thanks to the posters who took the time to upload them, but I cannot make out the markings on the IC U1.

Anyone able to shed any light on this?

Thanks again.

Hello Febman,
the U1 IC type is : VIPer22A
it is a 9V to 38V, DIP-8
Low Power OFF-Line SMPS Primary Switcher

You can find more infos on the Web by googling the type.
It can be found by Mouser or DigiKey for example.

Best regards,

Hello Febman
hope the service manual helping you finding out the defective components. If you have any feed back that can help other people, please be free to share it.
Best regards and happy Eastern to everybody,

Hello guys,

May I ask you to publish or send a private message with schematic and service manual for 2200E?

Best regards,
Pavel

Hello all,
please don't ask me to publish SM here, i don't want to be responsible for any copyright infringement, its a Cyberpower authority
i can send to moderators and then forum badcaps.net can be responsible

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. Looking into the unit again,the charging voltage without batteries, power off; is ok at 27.4Vdc. I found the charging current is not stable but by short pulse of 200 to 300mA, and current flows from one side + to the other -. More on the discharging than charging. Leading to slowly discharging the batteries.
Measuring caps, they are all good this time. Finally found that the D6 Diode (RL207 700V 2A) ,near the IC U1 VIPer22A, is defect. Got about 190 ohms resistor. Changing this to one with one of my stock (the RL207 is obsolete and can be replaced, by example, by a 2A07G or 2407GH), and the problem is now fixed. The normal charging current is stable at about 0.4A and slowly decrease up to 0.03A when batteries are fully charged and voltage is 27.4Vdc.
Hope this can help other people facing the similar issue.
