# What is the power plug in the photo called?

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

• 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? – Marcus Müller Mar 4 '18 at 13:02
• It's not a standard type. See IEC 60320. – Transistor Mar 4 '18 at 13:26
• Is this from china? it looks like a Type-I connection (used in china and australia) but within a standard IEC body – JonRB Mar 4 '18 at 14:02
• 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. – Criggie Mar 5 '18 at 0:55
• 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. – Criggie Mar 5 '18 at 0:56

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:

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.

• I could see that coming. +1 – Janka Mar 4 '18 at 15:07
• I don't see diagonal blades on your picture nor in the link. Can you explain how this answers the question? – Andy aka Mar 4 '18 at 15:29
• @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! – peufeu Mar 4 '18 at 15:47
• @Andyaka It's also the wrong gender. You're supposed to use the loose quick connects on the non-standard plug. – Jeroen3 Mar 4 '18 at 15:56
• 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... – rackandboneman Mar 5 '18 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.

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

• this design has to be changed for esthetic reasons. it triggers the facial expression recognition circuits in my brain and makes me depressed. – dlatikay Mar 4 '18 at 19:27
• Now that you mention it, I see it as well. It's is a truly sad design for an electric outlet :-) . – crj11 Mar 4 '18 at 19:28
• And that image is identical arrangement to an Australia/New Zealand power connector. And the same as China although rotated 180 degrees. – Criggie Mar 5 '18 at 0:54
