## Questions & Answers

**Q: I connected this to a 4.3 amp Fantastic RV fan to save energy.  However now the motor whines at low speed at the PWM freq.  How can I stop the noise?**
A: You might cure that with a capacitor with a voltage rating higher than the supply voltage, and perhaps a capacity rating of 100 mfd.  This capacitor type is polarity rated, so you would need to put it across the terminals going to the fan in way you are supplying the voltage.  You would also have to be sure not to reverse the power to make the fan go the other direction.  capacitor could probably be as low as 20 mfd. It can be placed anywhere in the line, or right at the fan.  The capacitor should smooth out the chopping voltage.  As scott says, it might not list to run on low power.

**Q: can this contoller switch be used for a razor motor scooter E 300 is 300 watts but if i put a 12 volt battery???**
A: No. Your scooter will require a controller that will handle at least 25 amps (the formula is 300 watts, divided by 12 volts, equals 25 amps). This controller is rated at 3 amps continuous and 4 amps peak -  at 12 volts that's only 36 watts continuous.

**Q: I want to build an electric scooter.  Is this a good reverse and speed controler for a DC 12v motor and battery**
A: Actually - No, not if it's something you want to ride on.  The circuitry in this is simply not heavy duty enough to handle that kind of load or that large a motor.  This circuit is intended for something on the order of a toy motor, no more than an amp or two at most.

**Q: Can anyone help me find a wiring diagram for this item please.**
A: The third picture shows how to connect the power supply and the motor. That should be all you need.
