View Full Version : Lowering Voltage on Power Supplies?

01-16-2004, 07:44 PM
Howdy all,
Here is what I got.

My 1100 oz/in servos are rated @ 48 VDC .33 amps no load.
I'm using 320 Geckos.
Right now I've got two power supplies hooked up @ 52 VDC 16 amps.
I have three 52 VDC 8 amp power supplies available to me.

I'm getting 132 ipm with my 8 tpi ACME now on rapids which is livable but hey I can handle more.

Now if I hook two up to get 104 VDC how can I downgrade the volts to get 70 or so volts?

I was told a rheostat might work?
Any thoughts?

You don't want to supply more voltage to your servos if they are rated at 48 VDC, then use 48 VDC.

I did and I thought I'll just be happy with what I have.

Thanks for the response.....
