The dimmer LC filter is implementing a different circuit than previously shown. It can reduce dimmer "buzz" but probably won't eliminate it completely. - - - Updated - - - I would choose an EMI suppression choke according to the rated motor current (e.g. 0.5 A or what it is) and maximal available inductance,
There are ample schematics available on the net. Just google with "Simple dimmer" and im sure you'll be pileup with atleast a hundred results with circuits.
Look at "Lamp dimmer" circuits on the internet.These circuits are used to dim the lamp light by decreasing the voltage accross the lamp.There are also dimming IC circuits for this purpose.ICs are better in terms of wide range voltage adjustment.
Hi, for a triac dimmer you need a zero cross detection. Wit standard dimmer circuits this is managed by R, C and diac. ************ So you say it is blinking. Then you should have a circuit. Show us your schematic. (I think this is the most used sentence here). Without your schematic it is impossible to see where the blinking comes from. (...)
If an incandescent lamp burns out, a high short circuit current might flow. Triac dimmers that are not protected by a built-in fuse can be damaged in this situation. Flickering of incandescent lamp can indicate a defective triac control circuit. LED drivers aren't necessarily suited for dimmer operation. - - - Updated
I have doubt that what is constant current dimmability??? Means i want to dim the LED but the keeping the constant current then what mechanism i have to follow. So which are the way to LED dimmer with constant current.
I would like to construct a labview vi in order to send command to microcontroller (arduino) to trigger the circuits in order to modulate the intensity of halogen lamp.(using VISA serial) Could someone please advice on how to construct a labview vi. (using slider to control the intensity in labview).please refer to the below attachment. pls: LIF
up to 5 volt dc to 220 volt ac dimmer circuit required .pls help
i'm trying to combine these two circuits a. light/dark sensor b. dimmer but having problem to figure out how to control the dimmer using ldr in the 1st circuit and also i cant figure out why my relay doesnt work with 12v source. can someone help me.. sorry my basic knowledge in electrical is very low. :oops:
Start with these..................... Siemens S566B Electronic Touch dimmer

These heater fans are mostly using a shade-pole motor. It can be controlled to some extend with a phase angle control (as utilized in a light dimmer). Due to the fan load, the speed is some kind of self stabilizing. Some simple triac dimmer circuits sometimes have problems with inductive loads, some are even supplying DC voltage to it, you (...)
I would imagine that using ?cu and fet or triac is out of consideration? This would be perfect job for something like pic 10F series... There could be even solution with standard logic that I would recommend over any analog one for this app. There are dimmer circuits that utilize UJT's for ramping or Vdc control. Is this schoolwork that requires sp
where is the circuit ? upload it again. tips :- use fan dimmer before transformer , it is simple too
for my dimmer circuit , switch circuits , i want to use triac in place of relay along with this i also want to remove the bulky transformer (bcoz controlling circuits current is just 5mA- 15mA). and last controlling circuits contains micro-controller so , after switch on/off it should be not reset the controller . (...)
Hi, can you give me some circuits or ic's that can I use to build a touch lamp dimmer with 3 steps. ie. 1st touch low light, 2nd touch middle light, 3rd touch maximum light and 4th tuouch turns off. I had some circuits made with TT6061A but I cant find from where I can buy the chip ! thanks ron
please specify the working of your circuit.... using what do you want to control your dimmer and other things......
Hi all I made this circuit to be a light dimmer but it did not work. I use BT136 for the SCR and MOC3022 for optocoupler. Can you tell me what is the problem? may be I should use another SCR. I have tested this circuit with BT136. It worked. Most probably you must have interchanged MT1 and MT2 terminals of triac and tha
hello , i would like to use sound signal as an input and want to control a light dimmer with it . I wonder if you could help me with the circuit design...
