SVC/TNS series high-precision automatic three phase AC Voltage Stabilizer is composed of a combination of single phase series high-precision automatic stabilized power supplies. The individual phase regulation of three-phase ensures stable and safe voltage of each phase. The power grid input is three-phase four-wire system, with a star (Y-shaped) connection method.
The output can be three-phase four wire system or three-phase three-wire system, with three ammeters indicating the output current of each phase. Output line voltage of each phase is detected by a transfer switch and a voltmeter.
TNS series high-precision automatic three-phase AC voltage regulator with specifications of 20KVA and above are composed of three single-phase automatic voltage stabilizing power supplies of corresponding specifications, with auto-coupling type.
This series of voltage stabilizers is suitable for small and medium-sized electromechanical equipment, production lines, construction machinery, microcomputers, textiles, air conditioning, refrigerators, audio systems, televisions, lighting and other household appliances that require voltage stabilization in industries, agriculture, healthcare, broadcasting and television, communication, scientific research, culture, etc.
