Really, really hoping someone has a moment to help me here.
I have an HP R5000 UPS set to 240v output that I recently noticed outputs 113v on L1 and 127v on L2 when on battery power using a true RMS multimeter. I'm sure not all my devices connected use both phases, but my understanding is that the UPS should only have a 5% voltage tolerance when on battery power according to the manual. I thought that would mean the transformer would keep each leg in sync based on the reference to neutral but is that 5% spec just referring to the total voltage @ 240v? If that's the case, how do I balance these better so voltage is closer to 120 for each leg?
I must be doing something wrong.
