Macroplast Transformers are a reputed Servo Voltage Stabilizers Suppliers in India from 1 KVA to 5000 KVA uses Variable Auto Transformers and buck-boost Transformers along with Servo Motors to manufacturer these units. These voltage regulators are basically, high-speed electromechanical servo stabilizers that ensure constant output supply at pre-set or factory set levels. The output regulation is achieved by using a set of closed-loop systems in which a set portion of the output voltage is attained by comparing with stable reference voltages.
