I need to install a computer server in a server room where they have several power lines and require me to have a dual psu because on mainteinance they switch of one of the power lines and the computer should be able to conmute automatically to the other. The problem is that my server does not have a dual psu and it has a max power consumption of about 1250 W. I think a workaround could be to use a Filax 2 to conmute between the two lines to keep the computer up during those (unfrequent) mainteinance cuts.
The problem I find is that in all the sample configurations I see in the Victron webpage the auxiliary line is always fed with an inverter. I understand that the inverter can follow the main grid so that when the transfer happens the wave is already in sync with the main line, but the two lines used in the server room most problably correspond to two different phases of a three phase system and they will be out of sync for sure. Could that produce a problem when switching from one line to the other? For sure it will introduce some harmonics there but don’t know If that would be enough to cause problems…
Thanks in advance for any advice.
