I need a 2W 24V to 24V dc converter to insulate part of a circuit.
However, from our distributor I cannot find such a device (there are many 24-24V but the power is 1W or more than 5W which means wasting space on the board). However I found many 24V to +/-12V.
Is it possible to use the +Vout and -Vout without using the gnd output, to have 24V? I know that dual dc/dc's require simmetrical currents, so this condition should be satisfied in this case. Do you think I am right?
Thank you for your help
 

It is possible, but the DC-DC converter must be isolated. That is, the +/-12V ground must be isolated from the +24V input ground.
 

If you mean can you take power from a -12 - 0 - +12 inverter by using only the positive and negative outputs, leaving the 0V open circuit, yes it should work as long as both outputs have sufficient current rating.

Best way here is to give it a try, given that the currents will be the same as you are putting the o/p's in series, it should work fine. Regards, Orson Cart.
