2、 SVC and SVS series single-phase and three-phase high-precision fully automatic AC voltage regulators
1. Overview of voltage regulator
The SVC and SVS series high-precision fully automatic AC stabilized power supply consists of servo motors, contact type autotransformer regulators, automatic control circuits, and other components. It is a popular AC stabilized power supply that uses servo motors to drive carbon brushes to change the coil turns ratio of the regulator to achieve voltage stabilization. When the voltage of the power grid is unstable or the load power changes, the automatic control circuit drives the servo motor according to the change in output voltage, adjusts the position of the carbon brush on the contact type autotransformer, and adjusts the output voltage to the rated value to achieve automatic voltage stabilization. This series of power supplies has the advantages of wide voltage regulation range, high accuracy, undistorted output waveform, and high efficiency, and can adapt to various loads. This series of AC power supply products is widely used for voltage stabilization of electrical equipment such as computers and their peripherals, medical electronic instruments, communication and broadcasting equipment, air conditioners, industrial production lines, etc., and is also widely used for voltage stabilization and protection of household appliances. 2.
