2 Amp to 28 Amp Variable Auto Transformer is made using quality grade material to offer optimum performance for longer period of time. The Variable Auto Transformer is designed in a capacity range varying from 2AMP to 28AMP, which is ideal for step less, break less and continuous control of A.C voltage. The Variable Auto Transformer is suitable for operations of 415 V 3 Phase A.C. Supply and give output of 0 - 415 V or up to 470 V, when connected electrically in star and mechanically in tandem. 2 Amp to 28 Amp Variable Auto Transformer finds applications in laboratories and commercial fields.
