How do you test a triac
WebFeb 19, 2024 · Triac dimming is a physical dimming that starts from alternating current phase 0 and reducing the input voltage until the TRIAC dimmer goes on. The primary working technique is to control the conducting angle between each half-wave of the alternating current and transform it into a sinusoidal waveform. WebThe circuit shows a triac used as a simple static AC power switch providing an “ON”-“OFF” function similar in operation to the previous DC circuit. When switch SW1 is open, the triac …
