• Standard Design • Recognized to UL506 • C-UL Certified to CSA C22.2 No. 66 • From 250 VA to 1000VA • Other Power Ratings Available on Request Using an auto-transformer is always an economical solution when you need to step down the voltage from 230V to 120 V or vice versa, and the equipment already has a fully isolated transformer or when the components do not require an isolated transformer. The toroidal construction of an auto-transformer offers important advantages in comparison with an E/I lamination core transformer, like smaller physical size and weight, 30-70% reduction (depending on secondary voltage) and very low magnetic strayfields. The auto-transformer can be mounted horizontally using a steel washer or our Poly-Mount, a plastic insert, or an epoxy potted center with a 1/4' mounting hole. See our page for more information.
With its small size and weight, the auto-transformer can be installed easily in existing equipment or supplied in an optional enclosure with or without cord, plug and receptacle.

Introduction We have already received some good knowledge regarding in a couple of previous articles here in Bright Hub. We have studied how an AC mains voltage applied to the primary winding of a transformer is magnetically induced to its secondary winding. In this article we will learn how to design an autotransformer through simple manipulations of ordinary transformers and get them converted into auto transformers. These devices can be effectively used to step-up or step-down our AC mains voltage manually whenever required.
Understanding Auto Transformers through this simple Experiment An ordinary 0-24 volts/ 5 amps transformer, can easily be converted into an auto transformer. As it should be able to handle power up to 100 watts, a 5 ampere current rating becomes imperative. As in the case of any other transformer, it will consist of a primary input and a secondary step down winding. Interesting things start to happen when one end of the primary winding is connected to one of the two ends of the secondary winding as shown in the diagram.
The procedure of conversion is as follows: • Take the help of the diagram and connect the lower end of the primary winding to the upper end of the secondary winding to form an auto transformer. • Apply AC mains voltage to this connection and to the free end of the primary winding. • Measure the voltage across the free ends of the two windings. • The voltage at this point will be less than the input AC mains voltage by 24 volts. Thc Credit V1.91. • On the contrary, in the next auto transformer configuration, when both the lower ends of the transformer are joined and the above procedure followed, voltage will be higher than the input mains by 24 volts.

Principle of Operation Again referring to the diagram, due to the inherent property of transformers, the instantaneous polarity (since the AC is changing its polarity 50 to 60 times per second) of the current flowing through the primary winding will just be the opposite to that of the secondary winding at that instant.
Therefore when the opposite ends of the two windings are connected, the secondary voltage gets deducted from the applied input voltage. When similar ends are joined, the magnitude of the secondary voltage gets added to the input mains voltage, because in this case the instantaneous currents in both the windings are in the same direction or in favor of each other. If you are still confused regarding how to design an autotransformer, you simply need to stop thinking and start commenting (needs moderation and will take some time to appear).
