- Difference between electronic regulator and resistance regulator of a fan:-
Ans: - Resistance type Regulator uses
Resistance & a selector switch to control the voltage. Actually in
resistance type regulator the voltage control is done by voltage drop in resistance
(converted into heat energy), which causes energy loss/wastage at lower speeds.
Whereas Electronic Regulators uses Triac or SCR based circuit and controls the firing pulse to reduce the output voltage. Here power loss is less at low speed in comparison to resistance type regulator.
Only disadvantage in local or cheaper electronic regulators that at low speed Harmonic occurs which causes humming & heating up of Fan. Now a day’s Energy saver electronic regulators are also available which do not causes radio interference or harmonics.
