Various Uses of Step-Down Voltage Transformer

Posted by Samstores on March 14th, 2019

A voltage transformer is a stationary electromagnetic passive electrical device operating according to Faraday’s law of induction as it converts electrical energy from a particular value to another. It is able to accomplish that by linking two or more electrical circuits through a similar oscillating magnetic circuit, which the transformer generates itself. Transformers can either decrease or increase the current levels and voltage of their supply, without modifying the electrical power to be transferred and the frequency from one winding to the next through a magnetic circuit. One of the common transformers you are likely to use is the step-down voltage transformer.

Transformers step down or step up the voltage based on the ratios of the primary to secondary wire turns. The step-down voltage transformer is used to decrease the voltage of an electrical device from primary to secondary. A transformation ratio of the device is equal to the square root of the primary to secondary inductance ratio or L. This type of transformer is ideally used when you are plugging a low voltage appliance or circuit into a high voltage AC supply or electrical socket.

The purpose of the step-down voltage transformer is to keep your appliances running in good condition and ensure safety as it isolates the lower voltage AC supply from your mains. It can deliver high current at a lesser voltage from the mains for certain applications, like welding. Moreover, it can be practical when you need to match the high impedance output from a tube or solid-state amplifier to a low impedance headphone or speaker.

Step down voltage transformers are practical for a wide array of electrical devices and appliances running on 110 volts of power and they need to be plugged into a 220 volt or 240-volt electrical outlet. It minimizes the 220-volt electricity to become suitable for powering a 110-volt appliance. You may need this product if you have 110-volt appliances that you need to use abroad where 220 volts or 240 volts are the norms. Just make sure that the product is CE-certified and heavy-duty, so you can be sure that it can be used safely in foreign countries.
