I had to rent some electronics equipment because I don't have the use of the campus equipment due to winter break. The DC power supply I was provided is much fancier than what I need and they didn't have a simpler one so I'm stuck with this one. It's a Hewlett Packard 6621A System Power Supply. I read the instructions, but it wasn't clear on how to hook up the wires for what I want. I just need a positive voltage from 0 to 5 volts and a ground. I'm not sure what's meant by "commoning". I've attached a photo of one of the back panel connections.

Thanks,
Mike

 

V+ and V- are positive and ground, respectively. Post some context from the manual for "commoning".

 

I would have gone for +0V for ground and +V for the positive supply connection?

 

I would have gone for +0V for ground and +V for the positive supply connection?

Except that they don't have a sense terminal and -V does. From the manual:

 

I'm not sure what's meant by "commoning".

That was referring to stacking supplies to get a negative voltage.

 

Thanks everyone. I got it.

 

You get your output from the +V and -V terminals. The +S and -S are for remote sensing the output when it is critical the voltage at a remote load is correct. If your application is not very critical leave the jumpers where they are and forget them.

+OV and -OV are for over voltage sense and suppression by shorting the output. You can probably ignore that feature too.


Therefor, just connect to the + and - V terminals and you are good to go.

BTW I found the full manual on yahoo first page when searching for the HP6621A numBer.
