So I'm getting the 220V line installed early next week.

The receptacle will be an L6-30. I would like to go from that to a PDU that would be running two 2400W power supplies. Each 30A circuit will be running up to 4 Avalon 741s in the future), putting the max load at about 22 amps.

I've seen APC and Tripp Lite with a host of range as far as ratings, cost, and features.

What are you guys using and what have you had good/bad experience with?

im running 4x S9 with this with no issues

but its pricey, I am looking at other alternatives now, seems like 2nd hand used may be the way to go

I've used these in the past, and are slightly cheaper than the first one:

But as btc-haze pointed out - it's hard to beat eBay and picking up used ones on there.  The only thing I would want you about is if you're getting a smart PDU with power cycling, etc - I picked up a bunch of Tripp-Lite ones a while back so I could do remote rebooting when needed, and the stupid things only have a relay on one leg of the power.  Net result is that with some of the better server power supplies will continue to operate even if one leg goes down.

I haven’t used these or purchased from them *yet* but I am willing to give it a shot.

no need to pay the electrician for the 220V outlet.

Strange setup - haven't seen one like this before.  Keep in mind the C19 plug it's being fed by is typically only rated to 16A, so even though it says it's a 30A PDU, the cable they're using is only rated for a bit over half that.  Personally I'd avoid this and go with something that actually can support the breakered load - L6-30 is what you're looking for in terms of input cable.

Yeah after looking into it, it appears it tries to achieve some
Funky “fake 3 phase power” <- honestly don’t know what else I could say to explain my understanding of it.
With two 20 amp breakers or something.

I got some used ones by server technology for $70 on eBay.  Sentinel, they're awesome.  My units are at a data center so I use it to log in and check power, power cycle units, etc.  Highly recommended if you're running remotely.
