UPS repair 9PX2200IRT3U
(1/1)

Hi!

I have bought the UPS in the title sometime ago and now its showing 'charger error' not allowing me power on the load.
Now, before opening it up someone has maybe some schematics of the boards? Or a general advice when working out this specific problem?
The batteries are ok, all in the range of 12.44V to 13.2V amd on the UPS board full voltage is shown ~77V so the battery pack seems to be working correctly.

Thanks for helping me out!
