Thread: Question about 12v power supply with speed control

Tweet

With some advice from others about using this speed control with my ATX power supply I ordered this. It will be used on the 12v bar and will let me control the speed of my prop. My only question is how to install it. I dont have it yet so this question might be premature. Maybe I could figure it out as soon as I get it. But if any one has the way to splice this device in I would appreciate it. I am thinking it will just be put in line with the 12v hot wire. Thanks.

At the right hand side of the pictures there are 4 terminals. The control should come with at least a cut sheet showing which is which, but there should be 2 for 12/24V power input to the control and 2 for output going to the motor.

On the right side of the board are four spandard male spade connectors. You would attach corresponding female spade connectors to your motor and ATX. The spades are clearly marked + and - for your power supply connections. It does go in-line. If memory serves, the 12v wire is the yellow one.

Easy Peazy.

Oops - smoke beat me to it.

BTW - If you're going to use an ATX power supply, I would just put the Qkits board inside of it. It's small enough to fit. Just drill a small hole on one side to stick the pot shaft out and you're all set.
