Supply voltage adjustment, boosting of low lines and line voltage stabilization, either manually or automatically in automatic voltage stabilizers. The primary and secondary circuits therefore have a number of windings turns in common. Since the volts-per-turn is the same in both windings, each develops a voltage in proportion to its number of turns. In an autotransformer part of the current flows directly from the input to the output. Feature:- Power Rating - 28VA, Single Phase.
