Three Phase Servo Motor Automatic Voltage Regulator/Stabilizers

TNS Series 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.

TNS series high-precision AC voltage regulator has the function of direct power supply. It has many advantages such variety, fully specifications and beautiful appearance. It has the advantages of no waveform distortion, high efficiency, reliable performance, long-term operation, etc. It has short delay, overvoltage and other protection functions. It can add long delay and undervoltage protection according to the needs of users. The product can be widely used in any place of electricity, it is an ideal regulated power supply to ensure the normal operation of your electrical equipment.

TNS series high-precision automatic three phase AC regulated power supply is composed of single phase SVC (TND) series high precision automatic regulated power supply. Three phase and phase to phase adjustment ensures stable and safe voltage of each phase. The grid input is three phase four wire system. Star(Y-shaped) connection, the output can be used three-phase four wire system or three phase three wire system.
