I am thinking of buying some cheap stepper drivers and buying a separate power supply to power the drivers.
I want to use something like an old PC case which is all aluminum. The voltage supply Im eyeing is rated for high voltage output and obviously the voltage from the jack is standard 110V.
I dont know much and learning about power electronics.
Do I need to ground the metal enclosure for safety in case there is short circuit? If so do I just wire out something and connect the enclosure to the ground terminal for the power jack that goes into the wall?
Also, the power supply probably doesnt have a fuse. Should I be putting a fast/slow acting fuse on the power supply between the powersupply and the jack? If so how do I hook this up? The standard power jack has 3 connectors. do I need a fuse on both the remaining hot ends?
What other precautions do i need to take? I heard some AC fans have good power output. How do I hook that up to the right voltage so I dont damage the fan and that it turns on when I turn the driver box on? I think the power source has DC output. So do I hook the AC fan to the AC side in parallel perhaps with the power supply block?
