Electronic vs Ordinary Rheostat Regulator: Key Differences

Difference between Electronic regulator and ordinary rheostat regulator for fans

The difference between the electronic and ordinary regulator is that in electronic regulator power losses are less i.e. for as we decrease the speed the electronic regulator give the power needed for that particular speed but in case of ordinary rheostat type regulator the power wastage is same for every speed and no power is saved. In electronic regulator Triac is employed for speed controlled.by varying the firing angle speed is controlled but in rheostat control resistance is decreased by steps to achieve speed control.
