The 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%.
Functional Description
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.

INFINITE CONTROL | Top | ||||||||||||||||||||||||||||||||
The infinite control switch gives infinite control for non-inductive loads up to 15 Amps on 120 or 240 V-AC (cannot be used with an external contactor). It can be turned either to left or right to adjust proper heat from 0-100% wattage with infinite control over the first 50% of total wattage. Energized continuously in HI position, at other settings it delivers selected input level under control of a simple bimetal timer. Only 3 mounting holes are necessary to install the INFINITE CONTROL SWITCH in customer supplied box or panel. It is designed for use at ambient temperatures up to 85C.
