Jan 18, 2021 After great success modifying the 1200w HP HSTNS-PL11 on this thread, I got a bit excited (perhaps over excited) and thought I&39;d try something similar with the 1500w version, the HSTNS-PL33 aka 684532-B21 . Perhaps foolishly, I thought I&39;d be able to find a schematic pretty easily but it has so far eluded me - can anyone help, or point me .. . In fact, there are two steps needed to turn on the power supply Pull up the PRESENT pin 36 to 3.3 or 12 V using a resistor. Pull down the PSON pin 33 to GND (the above mentioned datasheet calls it "RTN"). The four pins needed for turning on the power supply the "right" way. Aug 19, 2021 Here you will find a list of compatible server power supplies for our 12 and 17 port 6 pin breakout boards. PSU MODEL. PSU PART NUMBERS. DPS-460EB A, 499249-001. HSTNS-PD14, 499250-101. HSTNS-PL14. 499250-201.. Oct 03, 2015 In both cases, once I float the 2nd unit, the output voltage drops. On the HSTNS-P11 it dropped about 1 volt and on the DPS-1200FB it dropped about 2 volts for outputs of about 11.5 and 10.5 respectively. I adjusted the output voltage pot on the DPS-1200FB but that had no positive effect. There are no pots on the HSTNS-P11 as far as I can tell..

I'm hoping leaving this topic alive will make hints come as my two PD-18's are now sitting on a shelf The same with two powerful & tiny Emerson 7001605-J000 (aka IBM 94Y81138114).
