Technical Field

[0001] The utility model relates to the technical field of voltage regulating equipment, in particular to a knob regulator for voltage regulation. Background Art

[0002] The voltage regulator can adjust the output value of the voltage to meet the needs of different electrical equipment. After the staff inserts the plug of the electrical equipment into the socket of the voltage regulator, they adjust the voltage by manually adjusting the voltage knob to ensure the safe operation of the equipment.

[0003] The output voltage of a linear voltage regulator can be adjusted by using a variable resistor. By adjusting the size of the variable resistor, the relative size of the internal resistance of the voltage regulator can be changed, thereby achieving control of the output voltage.

The adjustment back and forth does not change, which affects the use of electrical equipment. Utility Model Content
