How to Connect LED Transformer?

Devices referred to as 12v transformer or 24v LED transformer in the market are referred to as power supply models in terminology. LED power supply, LED power supply, LED transformer, LED driver, LED driver, LED adapter all mean the same thing. The important thing is that the input voltage, output voltage and power values match your needs. There are also varieties of constant current power supply or constant voltage power supply. In our article How to connect the LED transformer? you will find answers to the question.

 

It is also called transformer for power supply in the market. Although it is so customary, this nomenclature is actually incorrect. Let's still make the following explanation to understand the subject.

Difference Between Transformer and Power Supply

The transformer can be used for AC voltage amplification, reduction or isolation. Areas of use can be high voltage, medium voltage or low voltage. For example, to use 34.500 Volt high voltage network in building installation, you need to use a transformer that reduces 34,5kV electricity to 400 Volt AC. Similarly, you can also reduce 220V socket electricity to 24V AC. These transformer samples are step-down transformers.

The power supply provides DC voltage at its output. For example, you have 220 Volt AC normal socket electricity and you want to operate a 24 Volt DC LED lighting product. Since the power supply you will use gives DC output at the appropriate voltage value, the LED luminaire will work. The most commonly used power supply models provide DC energy at 12 volts or 24 volts.

In summary, the transformer adjusts the voltage level. In transformers, AC voltage is given as AC at the output. If a DC transformer is used, the input is DC and the output is DC current. There is no conversion in transformers.

The power supply both adjusts the voltage level and provides DC energy conversion. In fact, we can say that power supply models also contain a transformer as a function. It first adjusts the voltage level and then converts AC current into DC energy. Now bar LED transformer connection for the next one.

How to Connect LED Transformer

Online LED transformer connection or LED transformer connection diagram When you search for "power supply", you will see similar images. But the power supply you have may not be the same. Therefore, it is easiest to understand the basics.

You should read the LED driver. There are connection points such as L, N, earth symbol, -V, +V on the device. We have attached a table with all possible abbreviations for you below. Table how to connect a strip LED transformer? will answer your question.

Many power supplies can have more than one DC output. This does not increase the power of the power supply. It just means more connection points and easier installation. In this respect, you can get an advantageous use with more than one output.

Note We strongly recommend that you consult an electrician in wiring. Because you can calculate the power correctly, but you need to choose the right cable according to the distance during the installation phase. Otherwise, a thinner cable than it should be means a voltage drop. This causes light losses.

As you know, you can connect the bar led models together in series. However, it should not be forgotten that it is also important how much current the PCB board of the bar led model you use will carry. Therefore, you may need to feed with a cable independent of the power supply again from time to time from long metres.
