Breathtaking Fan Regulator Circuit Using Triac
To overcome this a simple fan regulator circuit that saves power is explained here.
Fan regulator circuit using triac. To overcome this a simple fan regulator circuit that saves power is explained here. Today our country is facing power crisis and as a power conservation measure the electricity boards insist upon the consumers to save power using appropriate devices like power factor correctors proportionate power derivative systems etc. Simple fan regulator circuit using triac and diac.
Article by electronics hub. T his is the circuit diagram of the simplest lamp dimmer or fan regulator. The circuit works by varying the firing angle of the triac.
This method provides the step less control of the fan speed by deriving the required amount of power from the main supply at a given instant. Pin a0 is showing lowest speed for the fan is driven through a transistor to moc3021 to ensure very low speed to ac fan is avoided. Standard configuration of moc3021 driving triac.
This type of voltage regulator is an energy saving device which uses triac diac and potentiometric resistance. The power supply phase line is connected with one terminal of fan and other terminal from fan is connected with regulator circuit here triac connected across the fan and neutral power line the gate terminal is connected with diac the capacitor 2a104j is an polymer capacitor which is connected with variable resistor these components are controls the voltage flow through the fan. Triac is a semiconductor device belonging to the family of thyristors.
Resistors r1 r2 and capacitor c2 are associated with this. Snubber circuit added for this inductive load. Hence the power is conserved rather than wasted unnecessarily.
Triac based in the triac based electronic fan regulator circuit there are mainly three components used. Simple fan regulator circuit using triac and diac the conventional voltage regulators waste a lot of power at low speed. This is directly used to control the speed by holding and releasing the current flow.
