BROUGHT power supplies are important in LEDs as they aid in converting high voltage, alternating electric current to low voltage, direct present. This ensures that your LEDs are protected from high voltage problems.
The supplies also protect your LEDs from voltage and current fluctuations. This further aids in protecting your LEDs from damage.
How To Buy The Items
There are many factors that you need to consider when buying LED power supplies. A few of the factors that you need to consider include:
Kind of supply: there are many types of supplies that you could go with. Two of the most common ones are: external and AC.
You can find two types of external supplies that you could go with: constant-current and constant-voltage supplies. Constant-current supplies require a fixed output current and a wide range of output voltages. Constant-voltage supplies on the other hand require fixed output voltage with maximum result current.
Maximum wattage: the national electrical code requires that you pair your supply with an LED that will uses 20% less than the maximum graded wattage. As rule of thumb, you should never pair your supply with an LED that will exceeds your supply’s maximum wattage.

This is to prevent overstressing the components of your supply.
Dimming: there are some supplies that are included with a dimming capability. With the current changes in technology, it’s wise that you go with supplies with a dimming ability. When making your purchase, you should first test your supply and ensure that it’s working perfectly. Here you need to take a look at the external dimmer and ensure that it’s operating perfectly.
Power factor: the power element describes how a supply uses electricity. To calculate the power factor you need to divide the power being used by the supply by the input voltage. You should after that multiply the figure you get using the current going in. For ideal results, you should go with a supply using a power factor of 0. nine and above.
This is what you should know about LED power supplies. For your supplies to last for a long time you need to ensure that they are of high quality. This requires you to do your research and come up with a list of the reputable sellers in your area. If you aren’t sure of how to identify a superior quality LED power supply, you should consult a professional and ask him/her to help you out.
