Power supply

I have a power supply that has 3 output. 5V(floating),12V and -12V. How can I get 1 output of +24V from that power supply?

Hi,
What about using the -12v as Ground and the +12v as 24v!! If there's a GND output just ignore it.
Try it with a DMM it should just read as 24V..... It may depend of how much current you need?
