TDGC/TDGC2 Series Single-Phase Contact Voltage Regulators

The voltage regulator is of the adjustable autotransformer structure; the coil is evenly wound on the ring core, the electric brush is in close contact with the polished surface of the coil wire under the action of spring pressure, and the carbon brush is driven by rotating the shaft to make the electric brush slide along the surface of the coil, changing the brush contact position; that is, by changing the primary and secondary turns ratio of the transformer, the output voltage can be smoothly and steplessly adjusted in the voltage regulation range.
