The voltage stabilizer is composed of a constant voltage, a control circuit, and a bai 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. The coil turns ratio is automatically adjusted to keep the output voltage stable.
Automatic AC voltage regulator, its structure is composed of a contact type auto-coupling regulator, servo-type motor, automatic control circuit, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor to adjust the auto-coupling adjustment The position of the carbon brush of the generator enables the output voltage to be adjusted to the rated value and reach a stable state.
The three-phase high-precision automatic AC voltage stabilizer is a combination of the performance of the SVC series single-phase products. Its input phase system is divided into a three-phase four-wire system, and the output voltage is line voltage 380V within the rated capacitance range. Three-phase 380V electrical equipment is used and has an overvoltage protection function.

A voltage stabilizer is a power supply circuit or power supply equipment that can automatically adjust the output voltage. Its function is to stabilize the power supply voltage that fluctuates greatly and does not meet the requirements of electrical equipment within its set value range so that various circuits or electrical appliances The equipment can work normally under the rated working voltage. The original power regulator relied on the jump of the relay to stabilize the voltage.
When the grid voltage fluctuates(Washing machine stabilizer), the automatic correction circuit of the power stabilizer is activated to activate the internal relay. Forcing the output voltage to stay near the set value, this circuit has the advantage of a simple circuit, but the disadvantage is that the voltage regulation accuracy is not high and every time the relay jumps and shifts, it will cause an instantaneous interruption of the power supply and cause spark interference.
This greatly interferes with the reading and writing work of computer equipment, and it is easy to cause wrong signals on the computer, and in severe cases, it will damage the hard disk. High-quality small voltage stabilizers mostly use the method of motor-driven carbon brushes to stabilize the voltage. This type of voltage stabilizer has little interference with electrical equipment and has relatively high voltage stabilization accuracy.
