We are engaged in manufacturing a wide range of variable auto transformers -open type, box type, motorized in single, two and three phases using quality raw material and technology. Variable transformers provide an adjustable output voltage whenever a continuous regulation of AC Voltages with load is necessary. Made from 2 amps to 300 amps in single coil and above 300 amps with ganged coil, we also develop auto transformer up to 60 amps both in air cooled and oil cooled models and above 60 amps in oil cooled models only. The normal output range is 0 to 270 volt in single phase and 0 to 470 volt in two and three phases. We also supply higher output voltage as per customer’s requirements with features such as voltmeter, ammeter, motorization, etc and tested as per IS 5142 Our wide range of variable auto transformer are suitable for educational institutions with all terminations to be outside.
