What does transformer, TNS SBW etc. mean?

TNS SBW are transformer models! According to their actual needs to buy can, do not care about these model letters! 1, TNS: high-precision automatic three-phase AC voltage regulator, single-phase TND (SVC) high-precision automatic voltage regulator combined, three-phase phase adjustment, to ensure that each phase of the voltage is stable and safe, the grid input for the three-phase four-wire system, the star (Y-shaped) connection, the output can be used for three-phase four-wire system or three-phase three-wire system, by the three ammeter Indicate the output current of each phase by three ammeters, by a changeover switch and a voltmeter shift to monitor the output line voltage of each phase. 2, SBW: three-phase AC power regulator, is designed to stabilize the AC voltage. When the distribution network circuit voltage fluctuations or load interference can automatically keep the output voltage stable. Compared with other forms of voltage stabilizers, has a large capacity, high efficiency, no waveform distortion, strong overload capacity, reliable operation, small size, light weight, easy to use and maintain, low price and can be adapted to a variety of loads and so on.
