POWER SUPPLY CHOICES
I’ve already spent some time on the Automat Facebook group gathering info and feedback, but it’s clear that there are quite a few basic points that those who have purchased the Dadamachine Automat as a basic circuit board need to know before they can try it out.
Let’s try to gather all the info here in this thread!
This needs to provide a regulated DC output via a 2.5mm by 5.5mm plug, with center positive.
Its output voltage can be anywhere between 9V and 24V, depending on what voltage solenoids you want to use.
However, the circuit board has a 6A fuse, so if you want to plug in the full complement of 12 solenoids, each one can only safely consume 0.5A (12 x 0.5A = 6A)
24V solenoids tend to consume less current that 12V ones (for instance), so if you want to use all 12 then buying 24V solenoids that each use 0.5A or less is the best solution. You will therefore need a PSU with a 24V output capable of 6A, which equates to 144 watts.
If on the other hand you only ever anticipate running a maximum of six solenoids then you can instead go for 12V 1A models, requiring a PSU with a 12V 6A capability (remember, you won’t be able to run any more of these solenoids, because you’ll burn out the Automat’s 6A fuse.
However, 12V 1A solenoids may be considerably cheaper, and a 12V 6A (72 watt) PSU will also be considerably cheaper than a 24V 144 watt one!
Hope this helps!
