48 volt DC power supplies

[luckylinux]

You can get AC power supplies, I just don’t have the experience with DC power to know if it would be a more cost effective solution over AC.

Well the PSU is the easy Part. Then you'd need a Rack / Case to install them. Plus AC Cables, DC Cables, DC Fuses / Breaker, Cable Glands, Terminals, Connectors, Crimping Tools, Heatshrink, etc

I cannot see at all what the Connector is. Maybe you are lucky and it's just a WAGO / Phoenix 3-Pole "Terminal Block" like Terminal, so not excessively expensive.



How much does the AC PSU Cost ?

It might be worth your Time if not the Price & Space of the Entire DC System ...

$50-$100 depending where you source them.

I have a 42U rack to put them in. Also have 2x AC pdu’s.

50-100 USD for each 660W PSU ? Or for a Set of 4x ?

If for each Piece then you'd be looking at 40 x 50 ... 100 USD ... Ouch: 2000 USD ... 4000 USD .

On the other Hand, with the Vertiv R48-3000e, given total Power of 24kW, you'd be looking at A BARE MINIMUM of 8 Units (24kW / 3kW / PSU), most likely 12 Units so that you don't overload all of them. So probably 12 x 70 EUR ~ 840 EUR. But then you need to add all the other stuff I mentioned, unless you want to feed 1 PSU -> 4 x PSU, then *MAYBE* you could just get some Wago Terminal Blocks to do the Distribution and wire using those.
