Questions & Answers
Upon examining this I discovered that the " K " after the 16 was supposed to indicate it was an 8 amp product. The reason I ordered it was for that reason. As soon as my box arrived it said it was a "16K", but the switch said it was only a "16", so it was only a 6 amp switch. It too is used on an attic fan that is used to cool the whole house. The system has been working fine for the past few weeks. I'm not an electrical expert, Over 2 amps on the draw side is quite a bit too much.
I doubt it. The control looks like it clips the sine wave to control the speed of the motor using a Triac. Clipped sine waves could have an adverse effect on the solid state controller's power supply. I personally would not see it as a good idea.
Data provided by the manufacturer states It is part of the KBWC Among the 16K ratings for Ampere, here are the results The KBWC with 6 Amp at 125 Vac is a great upgrade. A rating has been assigned to Ampere by 18K The voltage is 125 volts and the amperage is 8 amps. To the best of my knowledge It is normal for the DC Motor or AC Motor to draw 1 amp when it starts. A 9 Volt battery draws 5 Amps (it draws one and one -half times its rated ampere) for its rated ampere My suggestion to you is to purchase a 1/3 hp psc motor rated 5 amps at 125 volts. You should buy the motor Speed - The control that has rated amps is The multiplication of 5 Amp by one is 5 Amp. It takes 5 plus 7 to make The KBWC - 5Amp is the recommended model I suggest you buy. In this 18K it has a rating of 8 amps at 125 Vac which has a relative amperage of For a 7 amp device, 5 amps would be sufficient. In this case, 5 amperes are needed. As per my experience, I connected an AC Motor Speed Control with a rated Ampere of 20 amps @ 125 Vac to an AC Motor with a rated Ampere of 18 amps @ 125 Vac - the result was a mild short circuit. You're not alone I thank you for your help! The fuse in the Motor Speed Control burns out when this motor starts, and little smoke appears.
In fact, yes. When you turn the knob all the way counterclockwise, it will be The device lets me control one of our entire house fans. I find it to be very useful.

It came with my Air Vent model ASRHPWW roof mount attic fan, so I have to adjust its speed. Air Vent motors are PSC motors with a 4 HP rating. It draws 3 amps at 120 volts with a speed of 1550 revolutions per minute. In order to have a greater degree of serviceability, I purchased the 6 amp control. It came without a control at first so I tested the motor without it. If the fan was directly wired, it would pull three amps. There is an incoming voltage of 121 and a current of 43 amps. With a laser tach, I counted the fan RPM and it was 1670. As a next step, I installed This 16K control provides improved When the motor pulled full speed, fully CCW, it pulled 3 lb. There is 43 amps in the system. As of this writing, the voltage coming from the supply 1657 RPM was the speed at which the fan spun. By adjusting the control fully clockwise, I obtained the desired result. A draw of 3 amps remains unchanged. In the meantime, the RPM has As I wanted the fan speed to be slower, I adjusted the trim pot at the front of the case until it reached Using 3 amps, the amp draw remained the same. The dial is positioned in the middle According to the speed setting, the current draw was three amps. The fan speed was 1220 and the temperature was 43. A constant 3 amps was drawn at all times. This is a total of 43 when viewed at all speeds. There was harmonic hum from the fan motor as it acclimatized, but it did not rise to the rated temperature rise. When the engine was at full speed, there was barely any hum due to the turbulence noise. When the engine was at 830 RPM, the hum was more noticeable as the air noise diminished. This fan and its control were about 10 feet from a roof-top TV antenna when the motor was running at 830 RPM and the hum was the same volume as the air noise. TV noise or distortion was not evident in either the VHF or UHF broadcasts. I have found this control to be very economic and to function well in my application. My expectation is that the motor will operate properly for many years rather than just a few due to the lower amp draw that the motor will operate under full load.
The problem is. The fan starts to hum when I listen to it. A lot of heat comes up from the second floor of my house With the help of this product, I was able to control the speed of an in-line HVAC duct fan. Due to the nature of motors and the design of this type of controller, the product works great for what it is intended for however, my fan hums due to the nature of the motors and the design of the controller. As the speed of the switch is changing, the triac switching circuit will turn off at some point along the AC wave. Hum is more likely to be produced at lower speeds. It is a square wave to the motor that causes a great deal of harmonic distortion, overheating the motor and causing it to It is a waste of energy as far as heat and sound is concerned, however for the price it is hard to beat. As long as you are glad to have a motor hum and a hot motor.
My attic fan was controlled by it, so I only used it in the summer on really hot days when it cooled off in the evening and I needed to cool off the attic. In addition to running hot, some others have mentioned this as well. I found it too warm to start a fire but not quite hot enough to start one. As a whole, it worked fine for a short time, but it was not very durable.
A resonance problem I was experiencing has been resolved. Shaded pole motors (brushless) are designed to be used with these. In my pellet stove, I recently replaced the squirrel cage fan with a much larger unit. During the process of doing that, he "overdid it. ". Despite the larger fan, the heat exchanger was unable to handle all the air the larger fan produced, which caused the fan to cavitate and make this obnoxious high-pitched noise Sonic howl pitched at a high pitch. As I was pondering several mechanical options to reduce fan output, I decided to try this tool and it worked perfectly! The RPMs were slowed around 30% to find a sweet spot with no resonance and a good amount of airflow. This is mounted in a plastic junction box with male and female pigtails on top and the other end on top - It is then "in line" after the plug which plugs in the blower. Glued to the wall behind the stove, the box is attached with velcro tape. This is not exactly a fashion statement but rather a simple and functional one. of the nice things that you could put on this machine is that the rotary knob has an OFF detent that goes to 100%. Lowers then. The switch operates the same way as a conventional dimmer, only the transition from OFF to ON is constant rather than ramping up. This provides the maximum motor torque at startup. There is also a trim pot which can be accessed through the front plate in order to limit MINIMUM RPM. Despite playing with it, I didn't change it, as I wasn't certain what the ideal RPM setting would be before installing. Since I will be the only one messing with it, there is no need to worry. In the area with the best settings, I simply put a dot on the cover with a magic marker. In order to utilize this RPM controller effectively, it must be used within the upper 50% of the motor's When setting the torque down very low, you will lose torque, hear motor hum noise, and can even overheat the motor. A large part of this has to do with the type and size of the motor, as well as its design and rated RPM at full voltage.
I find that this device works perfectly for my small watt fireplace blower (less than 1 amp). There had been too much noise from the blower earlier. Just enough adjustment down here to eliminate most of the noise, but the motor still runs at a fast enough speed to create air flow that warms I can't speak to its reliability because I've only had it for a short time. It seems to me that the blower and controller should last a long time based on my use of it (just to shave a bit of motor speed off).
Finally, my garage vent fan has been hooked up after waiting for 30 days for the hoa to approve its installation. I have been using it for a while, but when I added the fan controller it varied the fan speed well, but created an incredibly loud buzzing noise when the fan is turned on. In addition to generating much more heat from the motor than a regular wall switch, it also provided a lot more power to the wall. The fan motor was prematurely burned out because I could not stand the noise and was worried about prematurely burning out my fan motor. Should they be able to assist me, I will contact the customer service department and update my review.
It has two minor issues. This is a high quality fan dimmer I used for a fireplace fan. The following issues need to be resolved 1. As you can see in the picture, the faceplate in the item description is not what you get. 3.
Despite its depth, it's not an easy In a shallow box in the wall, you may have trouble getting it in because there are mostly wires. It was necessary to order a deep faceplate to work around the Nevertheless, it overall works very well and there is even an adjustable low setting, which I did not expect at all.
The fan switch is great. When you click it on, it starts very fast, very loud, and the fan starts at full power, so you want to get it up to speed before you lower it to a setting you prefer. The faceplate has a bit of an old school look, but you can easily replace it. What a great idea!.
