Nov 2, 2024 · 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, …

Aug 4, 2023 · 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 …

Jul 26, 2022 · 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 …

May 26, 2024 · The triac that's connected to the heater T2 (terminals A1 & G), on the diode setting of the multimeter, reads .072, and the other triac T1 reads .037. The triac numbers are:

Nov 8, 2020 · 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.

Aug 29, 2023 · The above waveform attached shows input sinewave which is stepped down using transformer and I am using voltage based zero cross detection for firing Triac. Above waveform …

Dec 5, 2022 · Hi everyone, I want to develop a soft start system for the receiver. In real system, it is a power supply in the laboratory with a variable resistance value - hence programming the resistance …

Dec 8, 2017 · I have searched online in attempt to see how I can setup my spice model to run a simulation on a triac. But I keep getting this error: "Unknown subcircuit called in: xu1 n003 n004 0 …

Oct 20, 2016 · The Triac needs a maximum of 10mA gate current, the supply is 230V, so with R1at 10K, R2+3 needs to drop 130V, which gives 13K total at 1.5W.. simple ohms law

Jan 18, 2022 · Hello, I made this circuit so I can control a 24VAC sprinkler solenoid valve (rain bird ones from home depot), using a microcontroller. I also want to mention that I am new to using triacs by the …
