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 for using a three-phase variac transformer

The load power of the voltage regulator is not fixed, the lower the output voltage regulation, the smaller the load power, please note that the equipment power must be within the load power of the voltage regulator. Specific conversion method: voltage regulator load power = output voltage X rated current.
