    Default Serial Connection of two power supply

    We use two S-150-24(+24Vdc, 6.5A), there are four terminals for the two
    power supply, Gnd_1,+24V_1, Gnd_2, +24V_2, then Use Gnd_1 as common
    ground, and CONNECTING +24V_1 with Gnd_2, and use +24V_2 as +48Vdc
    output.
    That will be a +48Vdc, 6.5A power supply by using two +24Vdc, 6.5A power
    supplys.
    We have used this +48Vdc,6.5A power supply to power up Dyn2 AC servo
    from www.dmm-tech.com

    This idea is good, my friend is an electronic engineer and he said all I have to do is isolate the DC circuit from earthing to the case and make sure all the power supplies have the same amp rating.
    I'm getting 48vdc and 14amps for 3 1200oz steppers from scrap pc parts!!!!
    God bless IBM!

    Thanks for this thread very useful.

    Is there any problems with connecting two 400w supplies together (parallel) with one output of 12.2 and the other 12.5?
