Single-phase output using a three-phase voltage regulator

When we have single-phase or three-phase electrical equipment, how do we choose the voltage stabilizer and whether we need to buy a voltage stabilizer each? When we choose a voltage stabilizer, we only need to see whether the voltage stabilizer can be connected to single-phase electrical equipment and three-phase electrical equipment. Among them, it mainly depends on whether the voltage stabilizer supports three-phase split adjustment.


The voltage stabilizer is composed of a voltage regulating circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage regulator. By automatically adjusting the coil turns ratio, the output voltage is kept stable. The voltage regulator with larger capacity also works on the principle of voltage compensation.

three-phase automatic voltage regulator

The single-phase voltage stabilizer is composed of a contact type auto-coupling voltage regulator, a servo motor, and an automatic control circuit. A Single-phase voltage regulator can ensure the normal operation of electrical equipment.

When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends out a signal and drives the servo motor, adjusts the position of the carbon brush of the auto-voltage regulator, so that the output voltage is adjusted to the rated value and reaches a stable state with overvoltage, Undervoltage, Overload, bypass, lightning protection, and other protection functions and waveform distortion, reliable performance, and long-term operation.


At present, three-phase voltage stabilizers can be divided into three-phase three-wire voltage stabilizers and three-phase four-wire voltage stabilizers, and we connect single-phase voltage stabilizers on the basis of three-phase voltage stabilizers, we need to choose Gute power three Phase four-wire voltage stabilizer when connected to single-phase, we need to connect one end to the live wire of the voltage stabilizer output end and one end to the zero lines of the voltage stabilizer output end.

The difference between the two lies in the input and output voltage and the number of access lines, and the internal structure and usage are also different. In use, the single-phase voltage stabilizer is only for single-phase electrical power supply, while the three-phase voltage stabilizer can be used to provide the three-phase power supply. It can also provide special requirements to the factory during production to provide a single-phase power supply.
