The difference between voltage regulator and voltage regulator

A voltage regulator is a power stabilization device designed to provide stable voltage in unstable power environments.
A voltage regulator is a voltage transformation device that changes the mains power to the voltage required by the equipment.
A voltage regulator is a device that changes the fluctuating and fluctuating voltage in all areas into a stable voltage for use. It reduces high voltage and increases low voltage to ensure that electrical equipment does not burn out and achieves stable voltage.
A voltage regulator is a type of voltage regulating power supply that can provide adjustable voltage to electrical loads. Its function is to transform the non adjustable distribution voltage of the power grid. For example, some electrical equipment cannot operate with the mains voltage of 220V and often needs to be connected to a power adapter. This power adapter acts as a voltage regulator
