Contact SupplierThe SME 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%.
The energy regulator mainly consists of a heated bimetal and a snap-action switch (spring contact). Fig. 1 below will make the mode of operation clear.
Normally the contact D is closed so that current flows through the heater winding on the bimetal and through the load. The bimetal warms and, in bending, opens the switch C, interrupting the current both to the heater winding and to the load.
The bimetal then cools and the cycle is repeated. The ratio of the time during which the contacts are made, to the total time of the cycle, determines the average input.
This ratio is controlled by the adjusting cam F. Clearly if the cam is set so that the contacts remain closed with the maximum deflection of the bimetal, the power will be permanently on; if the cam is turned until the contact D is open with the bimetal cold, the power will be permanently off. Between these two limits the input is continuously adjustable.
Since the same voltage is applied to the energy regulator as is applied to the load, any variation will affect the two similarly, so that the average input is independent of applied voltage over a wide range.
