    hey guys,

    I am building a project which needs to power a galvo amplifier, the amplifier needs a +-28V. I am trying to find a dc power supply that can provide me with a positive and a negative 28v supply rails but the maximum i've been able to find are ones that either give only positive voltages or the ones that do actually give both the positive and the negative rails only go upto 5V. And I've come across a lot of simple circuits that will probably allow me to do that but my supervisor needs for it to be an off the shelf product so it'd be great if someone could point me in the right direction. here's a link to a picture of what I've already got but this has a common negative terminal between the two outputs so i can't derive a negative rail off it.

    thanks
