Tips For Choosing A Step-Down Transformer

Step-down transformers permit any electrical item to be installed on 347V circuits, which is why many electrical specialists keep a few in their automobile stock. Selecting the right step-down transformer ensures the physical dimensions of the transformer are as little as possible to fit quickly in the junction box while keeping expenses as low as possible. Here are our pointers on selecting the best step-down transformer for your task.

What Is A Transformer And Why Is It Utilized?

A transformer is a static piece of electrical devices which transfers power from one voltage system to another by means of electromagnetic induction. At the fundamental level, all transformers include a metal coil which brings the electrical current and a ferrous core which creates the electromagnetic field. The reason for utilizing a transformer is to match the voltage of the load to the line voltage provided by the utility.

The dry type, air-cooled transformers consist of non-volatile, non-combustible products and depend just on the natural circulation of air over its coils, and the radiation of heat through its enclosure for cooling. For that reason, it might lie right at the load and requires no special vault. For Low and Medium Voltage Transformers Testing and Certification, visit this website.

How Do I Know If I Require A Step Up Or A Step-Down Voltage Converter Or A Transformer?

When you travel from the United States with your 110-volt gadget overseas to 220-volt countries( like Europe, Africa Asia etc), You will require a Step-Down Transformer or a Converter.

When you travel from a 220-volt country( Europe/Asia) to the U.S.A., you will need a Step Up Transformer or a Converter.

Likewise, there is Step UP/Down Transformers and converters readily available that work both as Step Up and Step Down. You will find a wide range of Action Up/down Transformers and converters on our website varying from 50 Watt to 20,000 Watts. These transformers enable making use of your electric devices throughout the world.

Remember to leave at least a 100% margin for power surges/spike when purchasing a transformer. For these items, you need to buy a voltage converter transformer that is at least 3 times the item’s capacity.

Our voltage transformers are made to transform single stage 110 or 220 volts. American 220 Volt includes 2 stages of 110 Volt and European 220 Volt consists of 1 phase of 220 volts.

Volts x Amps = Watts (i.e. 110V x 0.5 AMPS = 55W). Please make certain not to run any home appliance with greater wattage and voltage transformer’s wattage. This may harm both your appliance and the transformer! For sizing calculations, click here and use our Transformer Calculator.

Examine The Line Voltage

You may believe your line voltage is 347V, however, we measure it; it is difficult to be certain. Some line voltages are ranked 347V but experience voltage fluctuations bringing it as high as 400V+. These voltage fluctuations may too soon wear the step-down transformer and reduce its life process.

Decrease The Transformer Power Where Possible

Utilizing a 50W step-down transformer is always much better than utilizing a 100W version if your electrical item uses 40W. Once again, this makes installation easier considering that the transformer is smaller, and will cost less for the same result.

Confirm The Efficacy Of Your Step-Down Transformer

Step-down transformers have an effectiveness of 89%, indicating on a 50W transformer, you need to not set up a product of greater than ~ 44W. Constantly offer a little safety allowance by not maxing out the reliable power to ensure the transformer does not stop working.

Check The Physical Dimensions Of The Box/Housing As Compared To The Step-Down Transformer.

If your application does not have much room to house the transformer, the dimensions of the transformer are crucial to remaining compliant to code. Refer to suggestions 1 and 2 to reduce the physical size of the transformer.

Keep The Step-Down Transformers Physically Protected.

Step-down transformers consist primarily of coils of wire and magnets, and as such have an incredibly low rate of failure. Nevertheless, they are still vulnerable to physical damage if left in unguarded environments.

What Other Devices Are Required?

Together with the transformer, you will also need some other devices like a liquid level gauge, grounding resistors, lightning arrestors, pressure relief devices, etc. These devices are important to make sure the smooth and correct functioning of the transformer. Ask your provider to offer you the very same in addition to the duty to maintain these along with the transformer.

Is The Transformer Adequately Protected?

Transformers feature numerous precautions to avoid mishaps. It is recommended to check the transformer by hand before buying to ensure security. If you are uncertain, you can find guides online to understand everything about the precaution of a transformer. If it does not meet the commercial safety requirements, do not purchase the transformer. Click here for IEEE Standard Requirements for Instrument Transformers.
