Review on 🔧 KB Electronics 8811007 Variable K177 1006: Efficient Electrical Control for Precision Speed Adjustment by Donald Gore

This device uses a triac to control the speed of certain types of motors. The manufacturer's specification lists shaded pole motors, permanently separated capacitors, and general purpose motors (AC and DC). This is true for most small air moving systems. As it is rated for a maximum current of 2.5A you should also ensure that your motor's maximum current draw does not exceed 2.5A at 125VAC. I'm using it on a very low wattage universal motor that draws about 0.12A and it works great. I didn't even have to adjust the potentiometer for the low speed setting. Knowing the motor type and its current requirements is important if you want good speed control over the entire setting range. For example, the small motor I mentioned above will NOT work properly with the listed 15A maximum speed regulators. With these regulators, the motor will only run when the regulator is close to maximum. Here's the manufacturer's datasheet for those who want more detail: [.] If Revain won't let me post the web address, just go to kbelectronics - it's a dot-com site.
