Voltage regulator is a device to stabilize the output voltage. A voltage regulator consists of a voltage regulator 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, so that the position of the regulator's carbon brushes changes, and the output voltage is stabilized by automatically adjusting the coil turns ratio.
Unstable voltage can cause fatal injury or malfunction of the equipment, affecting the production, resulting in delayed delivery, quality instability and other aspects of the loss, so the use of voltage regulators, the use of electricity equipment, especially for the voltage requirements of strict high-tech and precision equipment is essential.

Product Classification
Voltage stabilizers are large-scale AC voltage stabilizers with a voltage range of tens of kilowatts to thousands of kilowatts. Thousands of kilowatts of AC voltage regulator, is to supply large-scale experiments and industrial, medical equipment, the work of the power supply. There are also small AC voltage stabilizers of a few watts to a few kilowatts, which are used to provide high-quality power for small laboratories or household appliances.
Based on the different nature of the output of the regulator, the regulator is generally divided into AC voltage regulator (AC voltage regulator) and DC voltage regulator (DC voltage regulator) two categories. The following focuses on DC regulated power supply, referred to as voltage stabilized power supply.
Based on the operating state of the regulator, the voltage regulator is often divided into two categories: linear voltage regulator and switching voltage regulator. In addition, there is a small power supply that uses a voltage regulator.
