The TNS/SWW series single and three-phase high-precision fully automatic AC voltage regulator is composed of a contact type autotransformer, servo motor, automatic control circuit, etc. When the grid voltage is unstable or the load changes, the automatic sampling control circuit sends a signal to drive the servo motor, adjust the position of the autotransformer carbon brush, and adjust the output voltage to the rated value and reach a stable state. This series of voltage regulators has a mains power through function. It has the advantages of multiple varieties, complete specifications, and beautiful appearance. It has the advantages of waveform distortion free, high efficiency, reliable performance, and long-term operation. It is equipped with short delay, overvoltage and other protection functions. Long delay and undervoltage protection functions can be added according to user needs. The product can be widely used in any electric field and is an ideal voltage regulator to ensure the normal operation of your electrical equipment.
The TNBISJW series high-precision fully automatic three-phase AC stabilized power supply is composed of a single-phase TND series high-precision automatic stabilized power supply combination, with three-phase phase adjustment to ensure stable and safe voltage of each phase. The power grid input is a three-phase four wire system, with a star (Y-shaped) connection. The output can be in a three-phase four wire system or a three-phase three wire system, with three ammeters indicating the output current of each phase, and a switch and a voltmeter shifting to detect the output line voltage of each phase.
