triac

Hi Guys, I have bought a triac which have a value of fusing current = 166 A2S for Tp=8.3ms mentioned in the data sheet I am wondering how can i check this value? Also , for the current pulse width triggering the TRIAC (0.5ms). Thank you for your support

Hi, I have to on-off switch a AC load, which delta connected 3 phase AC source. Consider the load that will be switched on-off is Z1. To achieve on-off switch, I think use zero cross triac opto driver and triac for both Phase-R and Phase-Y. But I am confused. When Phase-R reaches zero point...

Hello! Please help me validate the electrical design and the set of the components. The goal is to create removable modules that could switch the different types of payload: 1. DC MosFET module - switching and PWM of the 9-56V with 4A 2. AC MosFET module - switching and dimming (front and...

Bought Stairville PAR56 Active 300W and got a bit dissapointed in light output. So I got wondering maybe there is some mod I could do to put 500W 230V PAR56 bulb in it (originally 300W 230V PAR56) and not fry dimmer circuits. I traced schematic (look in attachments) in high voltage part, as it...

Hello all, New to the forum and came here to get some more information about simulating mains voltage Triac circuits. My issue is the following; I have an opto-isolated TRIAC control circuit for a resistive load (water boiler). I know that Triacs generally have a junction voltage drop of ~1-3V...

I have a bit of a problem with controlling a universal motor with a Triac. I have built the circuit shown in the attached picture (designed by someone else) and then I've written the software to control the firing of the Triac from an Arduino. It all works very well except that every now and...

Hello all, I'm currently doing some work on a piece of equipment which has been in my work's storage cupboard for about 8 years. On said piece of kit was this PCB that has seen better days (picture attached). I can't find any paperwork for it and it doesn't appear on any of my electrical...

Hi, I implemented the circuit from this video. After implementing, I realized a mistake, whenever the main supply switch turns on, there is an initial jerk (also visible in the video, the link starts video video from that point of issue) then triac operates as per gate voltage level on gate. Is...

I bought a damaged Lavazza coffee machine. After quick analysis I've found something in TO-92 case, which apparently exploded for unknown reason. It's literally in pieces, but I was able to find that the last letters describing the model were "8D" at the top and "30" at the bottom (see...

I build on bread board the attached schematic and I uploaded the attached code to an Arduino Uno. I tested each part of the schematic (the pot, the OpAmp, the zero crossing detector, the optotriac) and they are working. The problem is that when I start the circuit I got the attached screenshot...

Hi all, Is it ok to tie the output of multiple triac switching devices together to independently switch on a common load? I am looking to have multiple outside motion lights that are on my house, tied together so that if motion is detected in one area, that it turns the lights on on more than...
