Tips: What are the differences among a transformer, a voltage stabilizer and a voltage regulator?
A transformer can control the unstable voltage in a certain voltage range and protect the equipment from being damaged. A voltage regulator converts a specific voltage to the needed voltage of an equipment, each equipment should be equipped with a voltage regulator to prevent from burning out equipment caused by excessive voltage change. A voltage stabilizer is used to stabilize the voltage. Generally, a voltage regulator is a kind of test equipment that can change the voltage, while a voltage stabilizer can only adjust the voltage in a certain range. The voltage regulator can adjust the high voltage, but can’t insulate it, while the transformer is generally used to isolate, such as the isolation transformer, the transformer can be used to step up or step down the voltage. A voltage stabilizer is just a way to stabilize the voltage.
