you may have to many things plugged into the ups, it is not good to plug a power bar into one of the outlets of one of these as you are OVERLOADING the device with more power than it can produce

I have the same PCB on my Deltec PRR2200i. I at least know a few things about the circuit now. I had 11 transistors explode on mine and am replacing them now. Sadly I have not managed to track down a circuit diagram.
