The BHA Energy Regulator effects its control by periodically switching the power on and off, the ratio of the on time to the total time determining the average power input. As compared with a variable resistance, the energy regulator is in general cheaper, far less bulky, and applicable to any load up to its rated capacity. Moreover, the control is effected without the loss of energy associated with resistance control, is variable continuously from no load to full load and is substantially independent of mains voltage fluctuations up to about 20%.
Functional Description: The energy regulator mainly consists of
a heated bimetal and a snap-action switch (spring contact).
