Thread: DC Power Supply

  1. #1
    Trying to get a 5 axis machine running, just realised I can power the DC drives with a DC power source. Need between 90 and 150V and around 12A per axis (x 3) but will be OK with 1/3rd just for testing.

    Would anyone have one for sale or one I can rent / borrow to test with please? I'm Oxfordshire based.

    I think you could do this with a 110v yellow industrial PSU

    Then make a cable to a box to convert it to DC

    Bridge rectifier + Capacitors

    You will need to research what size capacitors and appropriate rectifier for the power input

    My Torloidial PSU build produced ~80v AC after you ran it through rectifier it dropped to 70v DC and capacitors smooth out the rectifier

    So I can't see why it wouldn't work

    If you didn't buy it from China the company you bought it from did ;)

    Thanks. I did the same later. One drive just spins and I Can control, the other trips the supply, no idea why but works on AC. I've given up on the system and started to retrofit.

    BTW, you still owe me an explanation on why you didnt come down on the weekend I had pencilled in to help you.
