Re: CP1500EPFCLCD - failure



Right. I have already checked all Mosfets and they are fine but I have decided to replace all of them and now I'm looking for what I consider being the controller: MC34063AL....

Re: CP1500EPFCLCD - failure



Sorry, I do not understand this part. You mean the light bulbs or the mosfets?...

Re: CP1500EPFCLCD - failure

Re: CP1500EPFCLCD - failure



Hi, I have just replaced Viper and all UF capacitors. The battery is charging, fuses are all ok, but I cannot make the UPS to switch from line to battery (test, unplug). I'll try to use the "bulb" method to see if there is something else....

Hi,

I hope these pictures are ok.

Thank you...

Hi all,

I have a Cyberpower CP1500EPFCLCD which is failing on battery test (power cord detached). There are no errors on LCD screen, no issues reported on PowerPanel software. Not sure if this is linked or not but I suspect that this behavior came after a thunderstorm although the UPS was connected to another AVR.
I have checked most of the components (no sign of burned components, capacitors looks good), mosfet checked, relays checked and working, batteries are ok but still not switching to invert the 24v DC to 220 AC.


Any help or schematic (even better)...
