Help: Programming a power supply using labview

[breedicj]

Recently I have been assigned the task at work of programming our TDK Lambda power supply with Labview. IE be able to adjust the voltage from 16V to 18V and adjust it back and forth by 1 V every minute for 1 hour. Any clue where to start, because I am a little lost?

Always check the NI IDN (Instrument Driver Network) and the website of the product before writing your own drivers.  9 times out of 10 they're already written for you.

Will this work with a ZUP (TDK Lambda) version power supply

The drivers listed in that link are on the TDK-Lambda web site.  I seriously doubt they would mix up their command structure.  From what I've seen, TDK follows the same SCPI protocol that Agilent does.

a little code to get you started...

ofcourse, this is stepping the voltage only and not ramping it....

Thank you so much man. I'll still need to make the program to commincate with the power supply, but at least that's one big hurdle out of my way 🙂

here's a ramp program....

presumably your talking over gpib, if this is the case visa writes to the specific gpib device work well.

e.g.

wire gpib::0::instr to the device input and to the write buffer *IDN? for example. You will need the manual though for the specific commands but they are probaly standard as said above

hope it gets you started
