Is there someone who now how to connect this unit
Wim5377,
I have spoken with HP techs and they assure me that this is not a standard HP product. However, it might have been manufactured for HP for a specialty item. At any rate, they fear that if you use this as a 48 volt linear amp the 57 amps rating will not be enough to keep the power supply from peaking, and in this case it would burn out. They would like to know any more info, such as the serial number, approximate size, and number of leads out if any.
As an alternative, you might consider posting this as a premium chat item, in which case you would pay for your answer, but would be guaranteed success. There are many experts in this field who may know the information you require, and the premium would attract attention much more quickly.

Dear Sir,
The PSU I bought is a HP 226519-001 supply.
These supply can used as a powersupply 48V 57A.
I bought the unit because I like to use it as powersupply for my homemade amplifier who needs 48V.
On the output-connector between the + and the - terminal of the unit are 20small pins for auxilary purpus. I think that On the backplane of the unit a several links are located.
where I am looking for is a schema, diagram or manual who telling me how and wat to connect so that I get 48V on the output.....
If I don't get the information, it seems to me that I bought a pice of trash wath belongs to the waste...
My last hope is that you can help me on the information.
If I have to pay for the information, so it be.
Let me no how match the fee is...
Kind regards
