[NSRCA-discussion] HP Server Power Supplies

[Ed Alt]

Ron:


Using HP 490594-001 as the search terms for Google, it turned up a number of hits.  I didn't check them all, but this one as an example looks promising, with data sheets and support manuals available for download.  It appears that the HP Common Slot power supply technology 3rd edition manual might answer your question

Subject: [NSRCA-discussion] HP Server Power Supplies

I have been converting server power supplies for our use for several years.  For the last year or so, I have been converting HP DPS-1200FB power supplies.  This power supply provides up to 75 amperes at 12 volts and they are about the size of a paperback book.

Recently, I ran across another HP server power supply.  There is no model number on this power supply.  Instead, on it is the following:  Regulatory Model No: HSTNS-PL11, Generic Part No:  490594-001, Part No:  4382032-001 and Spare Part No: 498152-001.  This power supply is the same size/shape as the DPS-1200FB and is also rated for 75 amperes at 12 volts.

I think it's strange that HP produced two server power supplies with the same same size/shape and performance.  Also curious is that the conversion process required to turn on the two power supplies is different.  The only conclusion I can come up with is that they were designed to be used with different servers, with different "turn on" circuitry.

Does anyone have more information about these two server power supplies?
