TNS (SVC) series three phase high precision AC automatic voltage stabilizer is composed of TND (AVR) single phase stabilizer to make the voltage of each phase stable, its input is 3-phase with 4-wire system and connect as star-type (Y Shape), and its output is 3-phase with 4-wire system or 3-phase with 3-wire system. Within the rated capacity range, it can be used for the equipment with source voltage is single-phase 220V or three-phase 380V. |
