Variable Auto Transformers

Single Phase Variable Auto Transformer takes the input from 240 V - 50 Hz AC line and the output can be varied from 0 - 270 V. The single phase variable auto transformers are available in projection mounting and flush mounting types. Output of these transformers can vary from 0 to 270 V with input being 240 V - 50 Hz AC. Ganged assemblies of 3 coils, connected in star are available for 3 phase supply. Contact arm of these coils are connected to common shaft. 3 phase variable auto transformer takes the input from 415 V - 50 Hz AC and the output can be varied from 0 to 470 V. The input of these variable auto transformers is 415 V - 50 Hz 3 phase AC and the output can be varied form 0 to 470 V. These transformers are fitted with voltmeter, ammeter, fuse, switch, pilot lamp etc. can be made in portable type models with extra cost.
