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: How does a three phase variac transformer work?
The working principle of the three-phase variac transformer is to connect a four-layer three-terminal semiconductor device between the power supply and the load, and with the corresponding trigger control circuit board, the voltage, current and power applied to the load can be adjusted. It is mainly used for heating power adjustment of various electric heating devices. It can be adjusted "manually" or cooperated with electric regulating instruments, intelligent regulating instruments, PLC and computer control systems to realize constant value or program control of heating temperature.
