	What is a Step Down Transformer? Devices that are used to step down electrical current at input power sources, which allows voltage to be compatible with equipment.
	Voltage Transformers Transformers that are designed for specific applications that need specified electrical voltage.
	Step Up Transformers A transformer that has the secondary winding higher than the primary allowing the transformer to increase input voltage.
	Power Transformers Devices that convert the incoming line voltage to a higher or lower electrical current to match voltage of equipment.
	Three Phase Transformers Transformers that are used throughout industry to change values of three phase voltage and current.
	Isolation Transformers Transformers that transfer energy from the alternating current supply to an electrical load.  They prevent certain types of harmonics.
	Buck Boost Transformers Buck Boost devices are used to make small adjustments to incoming voltages such as lighting applications.
	Phase Converters Devices that convert single phase power into three phase power.
	Acme Transformers Acme Transformers is an industrial leader offering superior service, quality products and technical service.
	Ace Phase Converters Ace Phase Converter has been in business for 25 years and their professional and experienced engineering staff can assist you with your phase converter application requirements.

Voltage Transformers

There are three different types of voltage transformers, low voltage, medium voltage and high voltage.  We will discuss each one of these later.  However, to understand the differences, you will first need to understand what a transformer is and how it works.

Transformers are electrical devices, which step up or step down incoming voltage at input sources. This is done by transferring energy from one circuit to the other through the magnetic core.  These windings are termed primary and secondary windings.  An electromagnetic field goes through a process of expanding and collapsing around the conductor.  This process changes the induced current with the formation of an output from the secondary coil, which either steps up or steps down the input voltage.

A good example of the use of a voltage transformer is when there is a piece of equipment that has a voltage of 110 Volts AC.  If you are in a country where the main power supply is 220 Volts AC, you will need a step down transformer to run your equipment.

What is the difference between a converter and a transformer?  Both are electric conversion products that enable you to run electric devices in different parts of the world.  If the device you are using is a high power heating element or mechanical motor such as a hair dryer or iron, you will need a converter.  But if your device is a computer, a printer or a VCR, you will need a transformer.

When purchasing a voltage transformer, always look for a quality manufacturer with experience in building quality transformers.  We recommend ACME or TEMCo Transformers.  They offer quality transformers combined  with a staff of expert engineers and technical support people to help you select the right transformer for your application.

Low Voltage Transformers:
One of the most popular uses of low voltage transformers are in the applications of landscaping.  Typically, they are designed to reduce 120 volts to an output voltage of 12 volts. It is important to understand that transformers can not stabilize voltage variations. They simply transfer the current at a fixed ratio and do not sense changes.

Medium Voltage Transformers:
Voltage transformers are usually connected directly to a primary distribution circuit and usually step down the voltage. There are many different types of medium voltage transformers such as liquid-filled, convention dry type and cast coil  just to name a few.

High Voltage Transformers:
These voltage transformers are usually used in power transmission applications used by utility companies.  They also are used in microwave ovens.  It is said that these transformers are the “muscle” of the microwave.  With a 120 VAC applied to the primary windings, the high voltage transformer steps up the primary voltage to a very high electrical current.  This high voltage is then boosted even higher by the capacitor and diode.

Always remember, when purchasing a voltage transformer, seek out a more reputable and experienced manufacturer such as  Acme Transformers . A quality manufacturer will save you money in the long run and will provide you with many years of quality service.

Step Down Transformers come in sizes as small as thumb nails to as large as big power grid units.
