As shown in the figure, three regulators TA1 , TA2, TA3 are connectedas star connection to expand pressure range and get the maximum attainable 433V voltage . The three regulators' X1, X2, X3 ends areconnected together, A1 , A2 , A3 are respectively connected to the 380V power's L1, L2, L3 three phases, so itobtains 433V at the output terminals Q1 and Q2 or Q2 or Q3 ends. This connection requires a three-phase voltage balance, TA1, TA2 and TA3 models and specifications must be the same.
