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 …

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.

Oct 20, 2025 · The current waveform shows your triac triggering half wave. That is because the gate resistor is far too small, and there isn't enough voltage across it to generate sufficient …

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 …

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 …

Aug 16, 2016 · Hello there, I'm looking around for a SPICE model of the MOC3063X optoisolator by Isocom, but I haven't tracked down a source on the web. Do you have a SPICE library, sub …

Nov 1, 2020 · A triac or SSR will drop about 1Volt, so will dissipate 1 Watt for each amp of current so you should check heat dissipation. Switching a DC solenoid with a MOSFET will incur less …

Jan 6, 2018 · These use a triac control readily, sometimes a bridge is added. All you need to do to confirm it is to lift or otherwise insulate one brush and measure the motor terminal resistance …

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 …

Mar 8, 2012 · Hello all! I am still a bit novice about electronics so i thought if someone could give some comments about this. I want to control a resistive heating element according to it's …
