variac variable transformer
TDGC2 Series Contact Type Voltage Regulator belongs to the Adjustable Variac/Autotransformer structure. The coil wound evenly on the toroidal core, the carbon brush holder installed in the spindle, under the pressure of spring, the carbon brush contacts the coil surface closely. Adjusting the spindle to drive the carbon brush holder to make the carbon brush move on the coil surface and change the carbon brush contact position, that is to say, changing the variac primary and secondary winding/turns ratio, which make the output voltage smoothly adjust with the adjustable range.
