Default Confusing about PDUs 1PH/3PH

I was looking at APC racks and PDUs.

I have 10 server which have a 1050W power supply each.
The server spec says:
Line Voltage (220) - Min 180Vrms - Rated 200-240Vrms - Max 264 Vrms

I need a PDU that will work for this.
Looking at a PDU that has
Nominal Input 208V 3PH

Nominal Output 208V

Would this work for the server?
If the input is 3PH, is the output single phase knowing that the connectors on it are C13 ?

Hi and welcome to the forums. Your assumption is correct. The PDU takes a 3 phase input and distributes single phase outputs on each phase. It is important to make sure the load is distributed across the three phases as evenly as possible, so a metered PDU is a good idea. Are you looking at something like their AP7869?
