Product DetailsThe TNS series high-precision automatic three-phase AC voltage regulator consists of three single-phase SVC regulators, employing three-phase independent regulation to ensure voltage stability for each phase. With three-phase four-wire star connection input and configurable three-phase four-wire/three-wire output, it features three ammeters for phase current monitoring and a voltage meter with change-over switch for line voltage detection. Units above 20kVA use autotransformer design, offering fast response (<1 second), high efficiency (>98%), and no waveform distortion, suitable for three-phase equipment voltage stabilization.
