I am currently using a AC-DC adaptor with specs:
- AC-I: 100-2040V~50/60Hz 1.6A
- DC-O: 12V 5A
Which is powering up 8 DC motors,
- 4× 12V 6W
- 4× 12V (wattage not specified, the motor is meant to be attached to a car battery)
How do I determine what fuse to use, and where to place it?
Do I place it after the adaptor and before the motors? And which fuse to use?
Do I place it before the adaptor, onto the AC current? And which fuse to use?
Can I place a fuse at both places?
I'd like to proect the system against all possible over-current scenarios.
