Step Up Transformer
A step-up transformer is one whose secondary voltage is greater than its primary voltage. This kind of transformer "steps up" the voltage applied to it. For instance, a step up transformer is needed to use a 220v product in a country with a 110v supply.
Step Down Transformer
Step Down Transformer is the opposite of step-up transformer, and used to run for example a 110v product in a country with a 220v mains supply.
Servokon offers an entire range of high quality Step Up/Step Down Transformers. This type of transformer is made of two or more coils of insulated wire wound around a core made of iron. When voltage is applied to primary coil it magnetizes the iron core, which induces a voltage in the secondary coil. The turns ratio of the two sets of windings determines the amount of voltage transformation.
With a step up transformer or step down transformer the voltage ratio between primary and secondary will mirror the "turns ratio". A practical application of this 2 to 1 turns ratio would be a 480 to 240 voltage step down. If the input were 440 volts then the output would be 220 volts. The ratio between input and output voltage will stay constant. Transformers should not be operated at voltages higher than the nameplate rating, but may be operated at lower voltages than rated. Because of this it become possible to do some non-standard applications using standard transformers.
Single phase transformers 1 kva and larger may also be reverse connected to step-down or step-up voltages. The primary components for voltage transformation are the transformer's core and coil. The insulation is placed between the turns of wire to prevent shorting to one another or to ground. This is typically comprised of mylar, nomex, kraft paper, varnish, or other materials. As a transformer has no moving parts, it will typically have a life expectancy between 20 and 25 years.
