Customer Questions & Answers
- Q1: If the power is cut off the unit will the momentary switch have to be pressed again or will the motor just start back up .
- A: Based from my experience, the switch is initially On all the time. So if power comes back there is no need to press the switch.
- Q2: Is there a soft or slow start feature in this unit?
- A: If the RPM is set to zero when it’s turned on you can slowly turn up RPM until fans start moving. I’ve got one of these running air circulation fans in my boat. It’s been going at 100% for a couple of months now.
- Q3: Can this reverse polarity to run my motor fwd and rev?
- A: It will not reverse a motors rotation, just controls speed.
- Q4: Can it operate a brushless fan motor?
- A: Sorry, probably not work, it can only operate brush motor.
- Q5: Also can you swap polarity on the output terminals
- A: If you mean can you reverse the motor without rewiring it, the answer is no. This is a single direction speed control only. It has no internal H Bridge that I can tell.
- Q6: What battery pack do i need to run this motor?
- A: What this is used for is to control the rams on a motor and I was using a 12v motor that generated electricity. This controlled the amount of rpms to put out the voltage I needed from the motor hooked to this to the amount of voltage I needed to run my generator motor. By increasing or decreasing the rpm I could go from say 10volts to 24 volts by using the rpm adjustment
- Q7: Can I replace the potentiometer with a 3 wire foot throttle?
- A: I think yes, just find if the pedal operates on the potentiometer.
