Steve,
A dual output AC/DC supply with even split loads like this is not as common as a lot of people think in the OEM market.
In the past we've handled these situations typically in one of three ways.
Option #1 would be to use two single output supplies. For this I would recommend either our ECS45 or ECM40 for the application. The datasheets for each are attached below and more information is available on our website at the links.
Option #2 is to use a triple (or quad) output supply that would have a +/-12V output as well. Typically the extra outputs (like 5V) are needed for some other aspect inside the system so it's actually beneficial to have it.
Option #3 would be to use a higher power 12V unit and then a dc/dc converter to split off the -12V power from the additional +12V power. This may save a bit of space over Option #1, but it's typically more expensive as a 36W dc/dc would typically cost more than a 40W ac/dc supply. Our JCP40 dc/dc converter could be an option for this along with our ECS100 for the main ac/dc supply. Those attachments are below as well.
As usual any of these options could be dependent on other details of your requirement such as thermals, quantities, performance, etc. I would be glad to speak to you in more detail on this if you would like. You can contact me via email at ksmith at xppower.com or you can find your local sales office and speak to a sales person there. The sales offices can be found on our website at: www.xppower.com
Thank-you very much.
