Triac Fan Regulator Circuit Diagram - 21 Images

The circuit works by varying the firing angle of the triac.

Triac fan regulator circuit diagram. Fan regulator is a device by which we can control the speed of rotation of the fan. Operation of the electronic voltage regulator circuit. The speed of the motor can be controlled by changing the setting of p1. In the triac based electronic fan regulator circuit there are mainly three components used.

Fan regulator is a very very much usable electrical or electronic device. Pin diagram of triac t1 z0607. T his is the circuit diagram of the simplest lamp dimmer or fan regulator. Before giving the power supply to this simple fan regulator circuit keep the variable resistor or potentiometer in maximum resistance position so that no triggering is applied to triac and hence the triac will be in cutoff mode.

This is 220v ac dimmer circuit diagram based on capacitor in the capacitive dimmer regulator no noise resistor one capacitor one diac and one triac. Today we are going to know how fan regulator works fan regulator internal circuit and fan regulator connection diagram. In this ceiling fan regulator circuit r1 500kω is a variable resistor that is used to adjust the fan speed capacitor c1 2a104j is a polyester film capacitor. Ceiling fan regulator ac dimmer electronic ceiling fan regulator ac light dimmer circuit we first discuss about the conventional big size resistive fan regulator conventional old ceiling fan regulators uses resistive wire to connect in series and there are multiple points to connect the regulating knop switch to adjust the speed.

This triac based 220v ac motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. Before giving the power supply to this simple fan regulator circuit keep the variable resistor or potentiometer in maximum resistance position so that no triggering is applied to triac and hence the triac will be in cutoff mode. Triac is very commonly used in places where ac power has to be controlled for example it is used in the speed regulators of ceiling fans ac bulb dimmer circuits etc. The setting of p1 determines the phase of the trigger pulse that fires the triac.

Operation of the electronic voltage regulator circuit. Triac is a semiconductor device belonging to the family of thyristors. Let us look into a simple triac switching circuit to understand how it works practically. The circuit diagram shown above is an classic example of a light dimmer switch where a triac has been utilized for controlling the intensity of light.

We will know how conventional fan regulator works internal. When ac mains is fed to the above circuit as per the setting of the pot c2 charges fully after a particular delay providing the necessary firing voltage to the diac. Here we have used the triac to turn on and off an ac load through a push button. The circuit is based on the principle of power control using a triac.
