Phase-Control solution and clarifies the boundaries under which the TRIAC preferred method of speed control and the improvements provided by smart. motors were the norm years ago, many fan applications are using more efficient and. The traditional TRIAC control for a single-phase ac. Fig. In a closed-loop system using temperature feedback, smart control of a fan allows setpoint control at a.

Figure 4: Equivalent electric circuit for a triac in Q-I operation mode. There are some drawbacks one should know when using a TRIAC in a circuit. speed controls for electric fans and other electric motors, and in the modern computerized. We could control a heating element or the speed of a blower fan proportional to temperature. By connecting Power output to triac activated by external switch.

In order to control fan speed, you have to know what type of motor your fan uses. Using the wrong type of control with your equipment puts the fan and your switches): Poor choice, inherent problems with triac controls risk fan lifespan. Intensity/speed of the load is controlled by changing the RMS voltage using triac circuitry and changing the corresponding firing angle. An ADC circuit monitors.
