    Tips: Can the voltage stabilizer increase the voltage?

    The voltage stabilizer can be divided into single-phase 220V and three-phase 380V. Whether it is single-phase or three-phase, it has the function of automatically increasing the voltage. The so-called professional term of increasing voltage is compensation voltage, that is, when the voltage is too low, the regulator will automatically compensate the missing voltage through the compensation package of internal isolation transformer, which is a complete process of voltage stabilizer increasing action.

    Then, what should we do when the voltage is too high? There is a contact voltage regulator inside. The voltage stabilizing system sends out a command that the carbon brush automatically slides on the voltage regulator to achieve the effect of voltage regulation and adjust to a stable voltage value. Therefore, the voltage stabilizer not only has the function of increasing the voltage, but also has the function of automatically reducing the voltage. When we leave the factory, we will set the voltage to the voltage value required by the equipment, and the voltage stabilizer will automatically adjust to the voltage value we set according to our requirements.
