Is the plug shown in the photo, which looks like IEC 320 but with angular tips, standard? If so what is it called?

    \$\begingroup\$ chances are that this is a proprietary backpanel connector, considering this looks like a server PSU. Manufacturer and type of device we're looking at? \$\endgroup\$ Commented Mar 4, 2018 at 13:02
  • \$\begingroup\$ It's not a standard type. See IEC 60320. \$\endgroup\$

  • \$\begingroup\$ Is this from china? it looks like a Type-I connection (used in china and australia) but within a standard IEC body \$\endgroup\$

    \$\begingroup\$ It is vaguely but not really like China or New Zealand or Australia's plug. For a start, its intended for a line cord not a direct wall socket connection. \$\endgroup\$

  • \$\begingroup\$ I'm guessing its a proprietary connector, because its intended for 277V AC which is beyond what most equipment would expect. So its HP being "safe" while charging a lot for the item. \$\endgroup\$

Apparently, there are HP server power supplies that have a non-standard connection.
They are found on ParallelMiner as KT-1200-200V-1 for example.

We use a custom 12inch power cord to bypass the proprietary AC plug

Behold the custom cable:

C13UNIVERSAL

It's just a cable with quick-connects.


Apparently this is the 277VAC version of the power supply:

HP 1200W Common Slot 277VAC Hot Plug Power Supply Kit (717359-B21).

The plug and socket are called LS-25 and LS-26. (an adapter is sold by stuartconnections)
HP also sells adapter TK801A and TK802A.

  • \$\begingroup\$ I don't see diagonal blades on your picture nor in the link. Can you explain how this answers the question? \$\endgroup\$

    \$\begingroup\$ @Andyaka Click "parallelminer" link in his answer. Basically HP seems to want $$$ for their custom connector, so everyone uses spade lug quick connects instead. Safety is our number one priority! \$\endgroup\$

    \$\begingroup\$ @Andyaka It's also the wrong gender. You're supposed to use the loose quick connects on the non-standard plug. \$\endgroup\$

    \$\begingroup\$ Not wrong gender - the other end is connected to a standard IEC cable it seems. What I hate about the makeshift cable shown is that the PE seems not substantially longer. BTW, that might not just be a cash grab - the standard C13/C14 system has a horrible tendency to be intermittent and too easily pulled/yanked out by accident, not at all fun around servers - and might also be out of ampacity if 1200W if there is an identical 110V version. Why ever they did not use C19/C20, though... \$\endgroup\$ Commented Mar 5, 2018 at 1:27

If you take a look at IEC World Plugs, it does look similar to an IEC Type I male connector, however, one of the blades is rotated 90 degrees.

enter image description here

My guess is that it is a proprietary connector to avoid the possibiility of connecting the supply without a cable from the manufacturer.

  • \$\begingroup\$ And that image is identical arrangement to an Australia/New Zealand power connector. And the same as China although rotated 180 degrees. \$\endgroup\$

The male inlet on the power supply is a LS-25. It accepts a power cord with a LS-26 connector/outlet.
