The AVR three-phase fully automatic AC voltage regulator is an upgraded version of the SVC series voltage regulator with more complete protection functions. When the voltage of the power grid is unstable or the load changes, the intelligent control circuit automatically samples the control circuit and sends a signal to automatically adjust the voltage, so that the output voltage is adjusted to the rated value and reaches a stable state. This product has the characteristics of waveform distortion, reliable performance, and long-term operation. It is equipped with overvoltage protection function. According to user needs, protection functions such as undervoltage and delay can be set up
High voltage accuracy and fast response. AVR can precisely control the voltage to ensure the stability of the output voltage.
It is able to adjust quickly when the load changes to meet the needs of different loads
High efficiency and energy saving. AVR regulators improve equipment efficiency and reduce energy consumption while maintaining stable output voltage,
helping to save energy and reduce electricity bills
Long service life and high reliability, by maintaining a stable output voltage,
AVR can extend the service life of the equipment and reduce the failure rate. It also has high reliability and low maintenance
Multi-function integration. Some AVR regulators have a variety of functions, such as lightning protection,
reactive power compensation, filtering, etc., which can greatly improve the overall performance of the power system
