This is a stabilizer. which constantly monitors the output voltage and controls the variations in the input voltage by movements of a motor. This motor in turn selects the proper output voltage on the variable transformer (variac). This is probably the cheapest power-conditioning product available. It gives reasonably good voltage regulation and is all right where voltage fluctuations are not considerable.
