Simple Electronic Fan Regulator Circuit PCB


Posted on Feb 5, 2014

Circuit The circuit diagram provided is a triac - diac electronic fan regulator that would reduce your power usage of electric fans even in slow speeds. A normal resistor-inductor fan regulator heats up to waste eneegy when the fan is running with lowers speeds or it controls motor speed via applying resistance between fan and power supply. This l

ight dimmer/fan regulator circuit uses the principle of power control using a Tric. The triac turns On and Off varying the firing angle of the Triac. This can be done by a diac oscillator circuit. The diac oscillator consists of D-32 diac, R1, RV1, R2 resistors, a 0. 1uF 400V capacitor. The time period of this diac oscillator can be controlled by adjusting RV1. By doing this we can vary the firing angle of the triac thus the speed of the fan motor.
