## Questions & Answers

**Q: Does the Potentiometer control the voltage or amperage?**
A: Amps.

**Q: I have a transformer that will provide 36 volts and 10 amps powering a full wave bridge.  Would the wave form of the rectified power cause an issue?**
A: Probably not but i have not tried it. If there was a problem you could parallel a capacitor with the 36 volts to filter the noise.

**Q: Is 100% command equivalent to running the motor directly connected to the power supply? My motors are not running as fast as expected.**
A: There will be voltage drop, it cannot be helped. There will always be resistances to the circuit, series-pass element(s), the circuit board itself, etc, so you will always lose something. If you need true 100% then you'll have to resort to a bypass relay for a "max" setting when required.

**Q: There is no fuse inside. What happens when it's overloaded? You must purchased another one? The 30a model at least has a 30a fuse inside the PCB.**
A: If you overload it, it's gonna fry the circuits everytime.I've bought a few of these just to experiment with. I've also blown up a few. For the price, they're great speed controllers if you use them properly.
