From farm design, manufacture, installation and maintenance, we can give you a turnery solution for your farm. 

Our single and three phase high precision automatic AC voltage regulator is composed of contact type auto voltage regulator, servo motor and automatic control circuit. When the grid voltage is unstable for the load changes, the automatic sampling control circuit sends a signal to drive the servo motor, adjust the position of the auto-coupler carbon brush, adjust the output voltage to the rated value and reach a steady state.
