Hi jimmykid,
The only DAQ modules we have that will output DC voltages that high are PXI modules which would require a PXI chassis as well. Here is a link where you can find some of these modules:

As you can see, this can get very costly. If you are using a Raspberry Pi, I am guessing these modules are outside the scope of your project budget.
However, you could find a third party power supply that will integrate in LabVIEW through NI-VISA and write a program to control the power supply. It would be up to you to find a power supply that would work for this. You will also need a DAQ device to read the signals from the Raspberry Pi. National Instruments has a lot of options for DAQ devices. Here is a link to some of our low-cost DAQ devices:

I hope this information helps!
