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.<span class="Apple-converted-space"> </span><br class=""><br class="">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.<span class="Apple-converted-space"> </span><br class=""><br class="">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.<br class=""><br class="">Does anyone have more information about these two server power supplies?<br class=""><br class="">Ron Van Putte<br class="">_______________________________________________<br class="">NSRCA-discussion mailing list<br class=""><a href="mailto:NSRCA-discussion@lists.nsrca.org" class="">NSRCA-discussion@lists.nsrca.org</a><br class=""><a href="http://lists.nsrca.org/mailman/listinfo/nsrca-discussion" id="LPlnk83535" class="">http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</a></div></span></font></div></div></div></blockquote></div><br class=""></div></body></html>
