APC sells a number of power distribution products world wide. All of our
European products are for 230 V phase-to-neutral loads. I have not run
into any 400 V phase-to-phase loads. The 400 V loads commonly used are
three-phase 400 V support products such as air conditioners.
Although power consumption of equipment is increasing leading to higher
currents, I would not expect 400 V input equipment any time soon. There
would need to be significant changes to the power supplies to support the
higher voltage. However, there is now research underway to go a different
direction: DC power distribution.

AM
Good people
In the US its typical for a large data center to run 208 Vac
rather than 120 Vac, and I just want to confirm I’m not going to run into a
similar change of voltage in European data centers. I assume that there is
no switch from 230 Vac, 50 Hz and phase to neutral.
Thanks
Gary
