User questions & answers

Question:	How do i wire this for 110? there is an in-n, in-l, out-l, out-n. i connected this on the hot leg to the in-n and out-n. fan runs but no speed change
Answer:	I used mine for varying the speed of a series wound "universal" motor. A motor with brushes and commutator. It worked to vary the speed. I wired it with the two terminals closest to the heat sink to the 110 the two closest to the variable resistor to the motor.
Question:	Which of the 4 screws are power/ground and in/out? They are not labeled
Answer:	I believe you want to know which terminal is power and neutral. Ground is not connected to any terminal, ground would be connected to the frame of the enclosure. This is an AC device, not DC. If you look on the printed circuit side of the board you will see one wire trace goes directly from one terminal to another terminal and no place else, those are the two neutral terminals. Refer to the diagram for line (input) and load (output) terminals.
Question:	Will this work in a led dimming circuit, between the ac mains and a dim able led driver
Answer:	"...LED's do not work with AC current" That is not true. Yes an LED is a diode and only conducts in one direction but that doesn't mean that it won't light up if hooked to an AC source. It will act like any diode and will only conduct on one half of the AC cycle. The 2 things to be considered are: 1. What is your "dim able led driver"? Is it meant to be driven by standard AC house current? If so, you're good to go. If it's expecting DC, then it might work but will only work with one half of the AC cycle. 2. The LED may produce light that is strobing at 60 cycles since it's off half the time. Not good for lighting. Great for headaches. Bottom line get a standard light dimmer switch.
Question:	Will this work to dim some 500w halogen work lights
Answer:	I think the answer would be "yes" with some constraints. "Yes" in that my experience has been it overheats at half the 2000 watt rating, but 500 watts should be OK. You should read up on halogen bulbs because unlike tungsten filament bulbs, halogens need to be operated at a certain minimum temperature. You should be able to dim them down to about 70% duty cycle as long as you also operate them at 100% for substantial periods at other times. Otherwise, I think you may have some condensation of tungsten on the glass tube surface. But as far as the wattage is concerned, this device should be ok t 500 watts. If you exceed its capacity it will have thermal shut down until it cools off. You won't have a huge investment if you decide to try it -- either in the PWM device or the tungsten bulbs. Just make sure you don't go below 70% duty cycle and check the bulb surface from time to time for evidence of metal deposits (silvering) and run at 100% duty cycle for a time to remove it. Good luck.

User questions & answers

Question:	can I use this dimmable switch for on and off in non dimmable gu10 leds
Answer:	Dear Customer,We only carry 110v models.Thanking you,EWO
Question:	I understand it wont dimm a non dimmable bulb, but would it work just for on and off funtion? I have a combination of dimmable and non dimmable lights
Answer:	It pops apart and is easy to clean.
Question:	will it work with a ceiling fan too
Answer:	It is significantly quieter than a Lasko 20" box fan on the same setting and distance(low, ~2 feet away.) On top of that, this fan collimates air(like a laser does to light, keeping it straight) out to(claimed) 50 feet. Sound follows the "inverse square law": double the distance, quarter the volume; 3x d = 1/9 v, 4x d = 1/16 v, and so on. So move it far away and enjoy the quiet.
Question:	Is this a smart light switch? Can it be controlled from my phone
Answer:	The 3rd review down answers that question, saying it has a 110 Volt plug on it. I run mine in front of the fire place insert three cold seasons day & night since March 27, 2019. I've only had to relube the shaft once when it got dry & slowed down. I have got my money worth, plus some out of it for sure.

Product description

We all know what an AC dimmer is; for those who don’t, it’s a kind of a circuit which can control the amount of AC voltage to be given to any device. You can see them in a fan regulator or a light dimmer switch.

It's good for a smart home if you need to turn the lighting on and off slowly. The lamp is slow damped, this creates a pleasant effect.

Also can control AC/DC motor, electric pump, tools.



Pulse Skip Modulation

Another way of doing this is by Pulse Skip Modulation. With PSM, one or more full cycles (sinuswaves) are transferred to the load and then one or more cycles are not. Though effective, it is not a good way to dim lights as there is a chance for flickering. Though it might be tempting, in PSM one should always allow a full sinuswave to be passed to the load, not a half sinus as in that case the load will be fed factually from DC which is not a good thing for most AC loads. The difference between leading edge cutting and PSM is mainly in the software: in both cases one will need a circuit that detects the zero crossing and that can control a triac.



A circuit that can do this is easy to build: The zero crossing is directly derived from the rectified mains AC lines – via an optocoupler of course- and gives a signal every time the wave goes through zero. Because the sine wave first goes through double phased rectification, the zero-crossing signal is given regardless whether the sinus wave goes up through zero or down through zero. This signal then can be used to trigger an interrupt in the Arduino.

User questions & answers

Question:	Can I use this to dim 12v AC at high current
Answer:	I don't believe there is on override. I own a couple of these great heaters and the only time I turn them on or off is when the temp permits, otherwise the unit turns itself off when it reaches the shut off temp.
Question:	What is the max wattage
Answer:	On high I believe it's 1500 Btu's and 750 Btu's on low. It has a fan that blows out the air pretty well. There is a thermostat on it so it shuts off when the room is at the desired temperature. We loved it so much this was the 2nd one we bought and the 2 of them heat our 1000 sq.ft. mobile home.
Question:	Is this a leading edge or trailing edge dimmer
Answer:	I have had this unit for 2 years. I am very satisfied with it in regards to noise and heat distribution. I have it in my basement covering approx. 300 square feet. The unit is quiet and does not get hot on the outside. I would recommend.
Question:	how to connect to raspberry pi
Answer:	According to the manual, on high heat it is 1500 watts. and 750 on low heat
