Tips for Buying Mains Transformer

The mains transformers are widely applied to convert mains voltage to lower voltages, low voltage lighting in particular. You may find that there are huge amount of makes and models for your option when you purchase your EI transformer. Here we would like to give you some tips before your purchase.

Firstly, ensure the transformer outputs the low voltage you demand. A very widespread type is definitely the 12v transformer (one that outputs 12v) but a lot of other voltages can be found. You won't do any damage if the voltage is lower than that necessary for your purpose, but it may not operate very effectively. On the other hand, in the event you feed 24v to something that demands 12v, you may damage the electronics heavily, so this is advice to get ideal mains transformers.

Secondly, know the energy rating of something you want to power. If it's halogen light bulbs, determine the amount of watts are consumed by each bulb and multiply that with the number of bulbs you are going to be making use of. That is definitely the minimum electrical power rating on the mains transformers you require. An excellent rule of thumb will possess small headroom in the electrical power, meaning that you could possibly have no less than 50% more energy out there in the transformer than you think you need. If your light bulbs consume 100 watts, then get a 150 watt transformer at the extremely least. You never know if someone in the long term will put more electrical power hungry bulbs in the technique, without the need of taking the capabilities of the transformer into consideration.

Thirdly, make sure what type of voltage you may need - AC or DC? A transformer only can output AC voltage, so if you require DC, what you truly want is actually what is called an energy supply. This can be a mains transformer and some added electronics. Also, do you need bipolar or unipolar outputs? A bipolar transformer has 3 output pins, which are known as the positive, the negative and common (ground). A unipolar transformer only has the positive and the common - this style is what's generally sold as a lower voltage lighting transformer, among other things.

Last, safety is another factor to be considered when installing the electronically appliance. The perfect solution is to ask a trained electrician or technician to install the transformer for you, however many people also can get the installing EI transformer done. Except one aspect – You should employ a professional to connect the transformer to the mains voltage. You must be careful that the mains voltages are lethal and very thick to function with components with low voltages.
