RE: [CAD_CAM_EDM_DRO] Re: Xylotex Pwr Sup replacement

Thanks Dave - Do you mean stay below the 24V of the current PS? So could I
temporarily go down to automotive voltage levels, and use either a gel cel
or lead acid battery with an automotive battery charger? I have several 6A
ish automotive chargers. Or break into a UPS and tap off the battery?
Thanks, C

you really need to keep the voltage lower.
remember that the decel of a drive will spike the power supply. fast decel
times can make the voltage jump.

if you can put your hands on a computer battery back-up, you can get some
high amps from the transformer.

also, a car charger will have a large transformer.

you will still need capacitors and diodes to get DC from these AC units.

you can lower the amp rating of the drive temporarally while waiting for the
perfect fix.

all electronics offers power supplies that are DC, you should be able to get
one in a few days.

the 24V 6A power supply gave up the ghost - just when we were FINALLY making
our first part for our FTC robot.

saw a 30V power supply on an HP printer the other day, but I'm thinking it
was only a couple amps. And I think I might have a 15-20V 4ish amp laptop
supply lying around.

this power supply board is only putting out like 1.5V? Should I be looking
for another set of stepper drivers too?
