Transformers & drivers

Halogen Transformers & Led Drivers

In simple terms, a transformer - often also called a transformer - is a device that 'transforms' voltage into another electrical voltage. A transformer is often used with lamps whose operating voltage differs from the mains voltage of a wall socket. For example, in most cases, a transformer converts mains power from 230 volts to 12 volts.

A transformer is needed when a low-voltage lamp is not equipped with its own transformer to adjust the mains voltage. In that situation, a transformer ensures that the lamp can still work despite the difference in voltage between the socket and the lamp.


LED transformers

LED transformers are useful devices used to adjust the voltage of Led Lighting to a lower voltage. Usually, the voltage is reduced to 12V.

Transformers contain an electronic circuit, a transformer and a driver that controls the current and adjusts the voltage. They are used to lower the light intensity of Led lights, because a lower voltage extends the (already long) life of the Led lights even more.


Buying a transformer, what should I look for?

Buying a transformer can be difficult for people who have no knowledge of such a device. That's why we have listed a few things to look out for when buying a transformer below.

Quality: Cheap is not always better. So choose a safe and reliable transformer. That way, you won't run any risks in terms of fire safety.
The required specifications: First, find out carefully what requirements the transformer has to meet. So check what voltage you need, as well as the necessary frequency and power.
The efficiency of the transformer: Nobody wants to have a transformer that is not efficient and loses a lot of current during conversion. Therefore, check carefully that the transformer you want to buy does not lose too much power.


What is the difference between a driver and a transformer?

A driver is an electrical device that produces a variable current, frequency or voltage during its operation. The device converts a signal into a variable voltage or current suitable for an electrical circuit. A driver is used to control or regulate another electrical device.

A transformer, on the other hand, is a device that converts a voltage from a high to a lower voltage or vice versa. Thus, this device is used to lower or raise the voltage level.


What kind of transformer do I need?

Exactly what kind of transformer you need depends on a number of different factors. You can buy many different types of transformers online or in shops, all of which have different functions. Depending on your wants and needs, you need to look for the right transformer for your appliances.

Before you can really start looking for the right and suitable transformer, you need to answer a number of questions, namely:

What kind of current do I need?
What wattages do I need?
How much power do I want?
Is the amount of power loss within my transformer of great importance?
In what environment will I place my transformer?

After answering these questions, you can start looking for a transformer that meets your requirements. At ET48, you will find a wide range of transformers so that you can buy a transformer that fully meets your requirements.


What types of transformer are there?

Transformers can generally be divided into two categories, namely electronic transformers and wound transformers.

Electrical transformers are light and compact, and should be placed close to the light spot. Thus, they should be placed a maximum of 1.5 metres from the spotlight. This is the only major disadvantage of electric transformers.

Wound transformers - unlike their electric counterparts - can indeed be placed further away from the spotlight. Like electric ones, wound transformers can be set with a timer and are dimmable.

The disadvantage of wound transformers is their size and weight. Compared to electric transformers, they are a lot bigger and heavier. This makes them less practical to use. Moreover, they need sufficient cooling, which means they cannot be used in warm rooms.

So it is up to you to weigh the advantages against the disadvantages. That way, you can make the right choice and choose a transformer that completely suits your needs.
