Thanks for all the help!  There's a person who post in "pictures of your rig" section who has 15 SP31 rack and I've been trying to get a hold of him to see how he has put it together.

Those PDU's won't work as your trying to put 73KW in one rack.

You will need a PDU with a IEC309 connector, those are good for 60A of 3PH and the PDU's can usually handle a little over 17KW.  You can get the extended rack enclosures that allow 2 of these per side so you would get 4 PDUs and 240A of rated power in the rack thats about as close as you will get, but if you stick to code you can only use 80% of the rated power 24/7.

Since you didn't ask for cooling advice I will just give you a side note.  Most Datacenters can not handle this amount of heat from one rack, you will be a glowing red violation when they do their thermal imaging check.

totally, have a friend with 3 MW in DC config , sadly he can maybe use 10% of it for BTC with his cooling arrangements . i like using * my power. nice PDUs though, I have lots of these.

You'll never get to 20 density in a single rack with normal "off the shelf" power parts, and most likely also not achieve cooling for it.  You're talking 140kw in a single rack, most US data centers top out at being able to handle 20-30kw per rack for cooling.

That being said, if you have enough cooling you could possibly make 16 per rack using something like an APC 9750 PDU.  The PDU you showed will be able to handle 2 SP-35's per.  But since it's a zero-u PDU you can only put 2 per rack thus only 4 total SP-35's.  You'll need to go with the horizontal ones to fit more. 

In this configuration you would have 2 units per 1 PDU so 16 Sp-35 and 8 PDUs would give you 40u used with 5u available.

so I would be at a heat load of 70 KW per rack rating. 

Shocked What is your proposed cooling arrangement, that's one hell of a density.

The specifications suggest those PDUs downrate to 24A for 24/7 usage, so keep that in mind. It makes them an awkward size as you'll only get 1.5 SP35s per PDU. I am unsure if there is an alternative though, hopefully someone will be along shortly to help.

Hi everyone

I want to set up a rack of Spondoolies Tech Sp35.  It's a 45u rack so I'd like to have 20 SP35s.  The power specs is listed below.   Would this pdu work for this situation?  Any ideas?

Thanks!

Three Phase Power. The panel  is a Siemans 3 phase load center, catalogue #G1224L312SCU Series A/ enclosure type 1. 125 amp max. 240 v rated for 3 phase. I can install single phase 30amp L6-30R plugs to keep cost down The SP-35s have a heat load of 3.5 KW, so I would be at a heat load of 70 KW per rack rating.
