1. The biggest function of the voltage regulator is that it can control the output voltage of electrical appliances with large current fluctuation within a certain range to ensure the smooth circuit and the normal use of electrical appliances. Unstable voltage will cause fatal injury or misoperation of the equipment, affect the use and unstable quality. Therefore, the use of voltage regulators is essential.
2. A voltage regulator is a device that stabilizes the output voltage. The voltage regulator is composed of voltage regulator, control circuit and 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 carbon brush of the voltage regulator changes, and the output voltage is kept stable by automatically adjusting the turns ratio of the coil.
3. The regulator has three functions:
(1) It protects the precision instruments with high voltage requirements.
(2) The experimental equipment (laboratory equipment) J of laboratories with higher standards are equipped with voltage regulators to ensure the accuracy level (accuracy) of experimental (laboratory) data.
(3) Key equipment in hospitals, national defense, factories, schools, finance and other departments are equipped with voltage regulators to ensure the stability and safety of equipment operation. And so on. In short, key departments in various industries apply voltage regulators to their key electrical equipment.
