    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.
