TND series single-phase high-precision automatic AC voltage regulator is composed of contact type auto-coupling voltage regulator, servo motor and automatic control circuit. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo. The motor adjusts the position of the auto-coupler carbon brush to adjust the output voltage to the rated value and reach a steady state.
TND3 series high-precision AC voltage regulator has the function of direct power supply. It has many advantages such as variety, full 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.Suitable for office equipment, test equipment, medical equipment, industrial automation equipment, household appliances, lighting systems, communication systems, etc.
