I have a pair of SURT 6Kva UPS units, each with the same model and type od APC step down transformer.I use an APC ATS (Auto Transfer Switch) across each transformer to provide redundant power to my 110v devices with a single power cord.
In the measurement section of the ATS, I see that the input voltages on each side wander around slightly, but always are about 5 volts off from each other.Here is what I see:
So, I looked in the UPS status pages on each UPS and I see less than 1v deviation between the output voltages of each.Like so...
Why would the voltage be so different at the ATS measurements page?Can I adjust this or "tune" it via some interface or by making some internal adjustment?
