Forgive what is probably a basic electronics question but ..
To keep my Phidgets cool I'm looking for a way to power a small computer style fan (probably 12v DC and 0.2amp). My options are ..
- A single 5amp, 12v DC supply which is shared between my Phidgets DC Motor and Servo controller boards.
A 12v DC 2amp power supply which is powering my LED controller.
I worry however that if I share either of these supplies with the fan, they'll fry the fan as they're delivering far too much current.
Any pointers are much appreciated.
