SPEED CONTROL OF FAN USING DIAC AND TRIAC

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. The fan regulators can be classified under the proportionate power derivative system as it derives only the required power from the main supply. Thus power is not wasted unnecessarily but is rather conserved. A considerable amount of power can be saved by using the electronic fan regulators. The cost of electronic fan regulators is higher than that of the conventional fan regulators. However, if proper steps are taken to educate the consumers about its long term benefit i.e. energy conservation etc., the market of this product is likely to grow.
