Prop-1 Power

[chuck]

Just a quick one! I am having to run 2 x 12v DC bty's in series, giving 24v and 3.6 amps, for the Prop-1 project, before I wire them in I would like to know if the amp's are too much. The circuit works as I have tested it with a 12v DC 'wall-wart' but need 24v for the pneumatics.

Thanks

You can't drive more amps into a device than it will demand if you maintain correct voltage.  The Prop-1 works fine at 24 volts.

Thats good news, thanks Jon.

Just check on your solenoids to make sure they don't require more than 6w at 24vdc -- if they do you may damage the ULN.
