After looking at the options NI have for this type of application, I think the solution you have come up with is about the best we can do. I tried doing a Google search for AC cPCI power supplies and did get a few hits. It may be worth your while checking that out yourself.
thanks for the suggestion, but it doesn't have the horses I need. I would really like an amp at +-12V.
I have found an alternative that the first post might also consider. It is the Geotest 7404. This card fuses and relay switches bus voltages and also monitors the output voltages and currents. It doesn't give me the 1 amp I desire, but it does provide +-12 at 500ma and 3.5v and 5v at 2 amps. it is not the precision supply card NI's 4110 is, but it looks like it what I need. Life would be easier if I had a larger chassis, but I'm stuck with an 8 slot and only one slot free.
Nice the Geotest 7404, but it is not programmable as the NI 4110, isn't it ?
In my case, this is an issue, as I need a fully controllable power supply.
The GeoTest GX7404 worked fine, but it did not have RT drivers at the time (available now???). I complained about buying a $1000 board I couldn't use and the folks were kind enough to send me a partial register map that I was able to use to energize the relays. The board has voltage/current monitoring capabilities that i can't use at the moment.
I wish NI would build a similar board. I would prefer to use it than a lab supply to power external circuits. Oh, and have I said how much I like snippets???
This snippet lets you turn off and on all of the relays. Note that the VISA resource name varies with your chassis and slot #.
Nice, I see
But then it is 1000 bugs for a fixed power supply with relays, isn't it ?
I mean, the Geotest is not programmable as the NI 4110.
