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: What is the difference between a contacting regulator and a transformer?

1. Different working principles: the input range of the voltage regulator is any sliding from 0V to the rated value range, and the point of the input voltage can be adjusted at any time to meet the stability of the output voltage. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage to achieve voltage conversion according to a certain transformation ratio.
2. Different properties: A transformer is an electrical device used for electrical energy conversion, which can convert alternating current energy of one voltage and current into another alternating current of voltage and current of the same frequency. Simply put, it is to convert different AC power into AC power of the same frequency.
3. The control motor is different: the working principle of the voltage regulator is the same as that of the transformer, the only difference is that it has a control motor, which can adjust the output voltage by changing the coil tie ratio.
