HP Compaq part 274843-001 3-phase modular power supply enclosure for ProLiant BL P-class blade servers, 51.4V, 342A, 17700W

This is actually a humongous power supply, which is fed by 2x 32A power current connections. This box delivers with the help of full six ESP120 power supply units 51.4V and current 171A + 171A. This totals up to 17700W... That is almost enough to feed a small electric arc furnace (well we do not guarantee that, but this is indeed a lot).

Here is a couple of ideas on what you can do with this monster power supply:

• Use it as it is to power up HP Compaq BL35-series server hardware
• Modify it/or it's power supplies for your purposes such as (a fast Googling will reveal some modification instructions. As you might have guessed modification voids any kind of a warranty.):
  • Electric car battery charger
  • Large UPS battery charger
  • Adjustable power supply (might require some individual trimming of each power module)
  • Power supply for large current in the region of 50VDC
  • Power supply for electrolysis
  • Power supply for electrochemical plating
  • Or as mentioned in the description, even as power supply for electric arc furnace, if you happen to be interested in small scale steel making.
• What ever you decide to do, do not kill yourself with this. We really want to have some business with you again in the future... And the point is, that there is high voltage present inside the power supply. Use a common sense, naturally primary side has some high voltages and even the 50V in the secondary side is something worth respecting. So know what you are doing!

We can decide upon these are these used or new. Most likely new, since we got a whole pile of new power supplies for them along with the units. This is unconditionally the most powerful power supply we have to offer or what we have ever seen so far.
