## Overview

The KB Electronics 8811006 is a UL & CSA approved solid-state variable speed AC motor controller designed for shaded pole and PSC motors. Operating at 115V with a max current of 2.5 amps, it fits standard 2" x 4" electrical wall boxes and offers infinite speed adjustment. Ideal for fans, blowers, and ventilators, it features built-in stall protection to prevent motor damage, delivering reliable, quiet, and efficient motor speed control for professional and home applications.

## Description

Control provides infinite variable speed for shaded pole and PSC motors. Max amps means that the rated motor name plate amperage can not exceed this rating or you will damage the control and motor. Motor must be run with sufficient torque to prevent stalling - A motor not turning will burn up Motor must have fan blade installed on shaft (direct drive) to cool motor. Not to be used with gear motors. Controls that have been installed are not returnable.

Review: Tested working, can't comment on longevity, but it effectively controls an AC motor. - Works so far. I was able to adjust it down to having it almost not be able to run the exhaust fan. Sadly the fan makes a lot of noise (seems angry) when it's barely running so I adjusted it to run at 50% at the lowest. I notice other commenters remarking that they can't get it to go low enough, make sure the Amperage of the version you buy fits the application. I got the 2.5 amp for something that will at most take 1 amp. So it worked pretty well. Documentation is meant for electricians it seems, but I figured it out.
Review: Works for AC fans at low speeds - I'm a licensed engineer. I have an attic-style fan that I installed to circulate warm air from my utility room to the living spaces rather than letting that heat it escape through the attic by conduction. To accomplish this, I set the fan up with a thermostat control to turn on above 90F, which keeps the utility room pleasantly warm and dry while also re-circulating the excess heat. The problem was that the fan was way too fast and too loud in the adjacent living spaces when it kicked on. I needed something to slow down the fan, which was a low wattage AC fan with a permanent capacitor across the line (little round guy on the power cord going to the motor). You can't use a dimer switch for this sort of application because it will burn up, and many fan controllers intended for ceiling fans won't work either because they have fixed detents for replicating industry standard speeds at low/medium/high. By contrast, this controller uses a solid-state component called a Triac to give you much more precise continuous control over the fan speed. Using this controller, I was able to lower the fan to a much slower speed than the standardized fan controls, allowing me to get the right balance of comfortable warm airflow and quiet noise levels. When doing this, it is important to realize that AC motors can stall if the voltage is lowered too much, and that they will burn up in place if they stall with power on. These motors need the airflow to keep themselves cool while running. This control has a fine adjustment for setting for the minimum fan speed, which prevents someone from accidentally stalling the motor with the knob alone. This minimum speed adjustment was essential for me to achieve the desired effect in my home while preventing the fan from lowering below stall speed. Overall, this controller allowed me to fine-tune my attic-style fan safely and make my home much more comfortable in the winter while saving me money on heating bills and reducing the heat level in my utility room.

## Questions & Answers

**Q: Will a 1300 watt 3 amp motor be able to be run on this switch?**
A: amps=Watts/sin(45)/Volts
1300[W]/sin(45)/120[V]=15.32Amps

Got to remember to do the root-mean-square when it's AC

**Q: Have the 5 amp model hooked up to hair dryer with heater disabled. Using just fan motor. The unit does not work to control speed. Any suggestions?**
A: isolate all power sources, check wiring connections hot to motor controller hot to black power , motor controller red to motor, neutral to neutral ie white to white, green to green. if the red out of controller is to hot wire it will not work and may have blown the controller if connected wrong and energized

**Q: Will this controller work with Panasonic’s whisper quiet model tnx**
A: I was not able to fine infomation on your Panasonic Whisper quite model TNX.  
Would it be possible for you to email product infomation.

Please email to b.tognan@kbelectronics.net

Thank you,

**Q: I have 2 hunter ceiling fans, wired in series.  the standard 3 speed lutron control from menards doesn't work (fans stall out).  what size/amperage?**
A: Assume you are asking how many amps your 2 fans are drawing.  Not much, but specs should be listed on fan instructions.  I ended up not using this motor control because of the humming noise it caused the fan motor to make.  Most people object to fan noise.  Controllers that do not make noise are very expensive, nearly equal to the cost of a good fan.  It would be ideal to use the speed control already in the fan if possible.  Just a thought.

### ⭐⭐⭐⭐ Fantastic Product
*by S***1 on June 28, 2018*

UPDATE0 first one only lasted two hrs when I adjusted the stall screw it just sizzled. 2nd one screw adjustment works just fine, but now my motor has a small hun, not bad, but I can hear it. First one was dead quiet till the adjustment sizzled out, But I still recommend these. Now matter how good a product is, there are bound to be a few defects. First off I had people telling me I could not use this on a Holmes window fan. Well I am glad they were wrong and I was right. This little baby works perfect, no noise, no heat and looks good. I even checked my fan motor for an increase in temperature, guess what, nope. And no funny motor noises as with most other speed control switches on the market. Simple and easy wiring. No adjustments were needed on the speed screw stall adjustment. I think everyone I spoke with said I would only get a max down to 70% some said 50% speed. Well I can go as low as I want with no ill effects. Most importantly doing that with no noise or heat issues is a huge bonus. So now my entry level Holmes fan with this controller is better than their most expensive so called adjustable fan. Cant say enough good things about this controller. If your wondering should you get this or something else, just get it.
