- Triac burn out - All About Circuits
Triac failures are usually caused by either excess current or excess voltage, either to the gate or through the device, and if they happen at the moment of turn on application it is most likely not overheating
- Half_burned triac - All About Circuits
Hi, In a dishwasher machine main board we have used 107NN0 triac for controlling ac loads such as valves, pumps, dispenser, etc In about 2 to 3 percent of products sold to customers, one of triacs that has a parallel RC equivalent load is half-burned (triac is short-circuited in one direction)
- triac model for ltspice - All About Circuits
anybody know where I can get a good triac model for use in ltspice simulation? been looking like forever got a diac model that works
- Triac light dimmer controlled with DC voltage - All About Circuits
I am looking for a way to make a "light dimmer" (actually controlling a heating coil) using a triac, where I can control the duty cycle of the AC based on a DC voltage In searching for such a circuit, I either find: 1) The basic light dimmer using a triac with a diac and a variable resistor
- I think my triac batch is defective | All About Circuits
Hello everyone I've designed a circuit for dimming lamps with a triac (home automation) Everything was great and I also manage to produce a small batch, that got sold and installed at some houses I always knew my product would cause some lamps to flicker, when operating on very specific
- Motor control using MOC3041 optocoupler | All About Circuits
The BW type triac is marketed as "snubberless" because it will withstand a high dV dt The opto-triac isn't quite as good with dV dt so best to keep the snubber, but zero-crossing opto-triacs will generally manage without
- triacs that work with zero crossing optocoupler drivers
This was not the case using a bta16-600b triac As this triac like many others require a 50ma current to switch on I assume that at zero crossing there is not enough current to switch on this triac Can anyone suggest which specific triacs will work with a zero crossing triac optocoupler driver? rs1000 is not available any more
- Controling a fan with a triac - All About Circuits
Hi, I'm doing a small project, in which I control a regular home fan from my processor I use a triac (BTA12-600BW3G) to shift the phase of the current and this way I can control the speed of a fan The triac is controled by an optoisolator with triac driver output (MOC3021) which is controlled
