LED power supplies are important in LEDs as they aid in converting high voltage, alternating current to low voltage, direct current. 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 Supplies
There are many factors that you need to consider when buying LED power supplies. Some of the factors that you need to consider include:
Type of supply: there are many types of supplies that you can go with. Two of the most common ones are: external and AC.
There are two types of external supplies that you can 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 output current.
Maximum wattage: the national electrical code requires that you pair your supply with an LED that uses 20% less than the maximum rated wattage. As rule of thumb, you should never pair your supply with an LED that exceeds your supply’s maximum wattage. This is to prevent overstressing the components of your supply.
Dimming: there are some supplies that come with a dimming capability. With the current changes in technology, it’s wise that you go with supplies with a dimming capability. 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 working perfectly.
Power factor: the power factor 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 then multiply the figure you get with the current going in. For ideal results, you should go with a supply with a power factor of 0.9 and above.
This is what you need to know about LED power supplies. For the supplies to last for a long time you should ensure that they are of high quality. This calls for 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 high quality LED power supply, you should consult a professional and ask him/her to help you out.
