Three Phase Manual Variable Auto Transformer
Variable Auto Transformer Manufactured By Purevolt Is The Most Useful And Effective Device For Step Less, Break Less And Continuous Control Of A.C Voltage And Therefore, For Control Of Various Other Parameters, Dependent On A.C Voltage. also called as dimmerstat they are used for testing purposes.
The Normal Output Range Is 0 To 270 Volt In Single Phase And 0 To 470 Volt In Three Phases. Three Such Variable Auto Transformer When Connected Electrically In Star & Mechanically In Tandem, Became Suitable For Operations Of 415 V 3 Phase A.C. Supply & To Give Output Of 0 – 415 V Or Upto 470 V.
We Are Engaged Into Manufacturing and Supplying of these Three Phase manually operated Variable Auto Transformer with Enclosure or without enclosure. The Normal Input Range Is 415v And the Output Is 0 – 470 V or up to 490 V. We Design And Develop these Three Phase Variable Transformers With Special Features Which Are Appropriate For Educational Institutions, Testing Labs, Etc. And In Oil Cooled Models, We Use Appropriate Radiators Enough To Control The Heat Of The Transformers.
We make these 3 Phase Manual Variable Auto Transformer in below ratings.Rating Available: 2 Amp to 600 Amp
