TNS series of high-precision fully automatic three-phase AC voltage stabilizers are composed of single-phase TND (SVC) series of high-precision fully automatic AC voltage stabilizers. The three phases are adjusted separately to ensure the stability and safety of each phase voltage and the power grid. The input is a three-phase four-wire system with star (Y-shaped) connection. The output can be a three-phase four-wire system or a three-phase three-wire system. Three ammeters indicate the current of each phase, and a button switch and a voltage Table shift detects input and output line voltage. The TNS series high-precision automatic three-phase AC voltage stabilizer with specifications of 20KVA and above is composed of three single-phase automatic voltage-stabilized power supplies of corresponding specifications and adopts auto-coupling type.
Widely used in communications, medical care, textiles, radio and television, precision instruments and various elevator systems and other places that require stable voltage power supply.
