    Wiring method

    Installation and use of three-phase variac transformer should be noted: the wiring must be firmly pressed, there can be no loose.

    Three-phase variac transformer is a three-phase four-wire system, the input side should be connected to the zero line, when using the regulator to adjust the voltage should be adjusted from 0V to high voltage, the output voltage is different corresponding to the load power is different.

    Tips: Classification of voltage regulators

    Voltage regulators are divided into five types: auto-coupling regulators, isolation regulators, oil-immersed induction regulators, column-type electric regulators and thyristor regulators. The working mode of the pressure regulator is divided into manual pressure regulation and electric pressure regulation.

    ATO Responded
    Unfortunately, we did not update the 480v input voltage on the website, because it needs to be customized.
    For parameters, please refer to this 3-phase variac transformer of 380V website.
    Only the voltage has changed in the parameters.
    Which input voltage can transformer work with?
    Thank you for confirming.
    And does it work with an input voltage of 380V and 480V?
