In recent years, LED strips have become a popular solution for lighting and decorating various spaces. However, in order for the LED strip to function reliably and efficiently, it is necessary to provide it with proper power supply. This is where the LED power supply plays a key role.
Why do you need a power supply?
A power supply for LED strip is a device specifically designed to convert and provide the required voltage for powering LEDs. These power supplies perform the function of voltage stabilization and protect the LED strip from overloads and short circuits.
How to choose a power supply for the LED strip?
When choosing a power supply for an LED strip, it is necessary to consider two main parameters: the voltage supply and the total power consumption of the LED lighting. For example, let's consider an SMD 3528 120 LED strip with a power consumption of 7.2 watts per meter, and assume that the length of the LED strip for the project is 20 meters.
The first parameter, voltage supply, is indicated on the packaging of the LED strip. In this case, it is 12 volts. Therefore, the "Mean Well" or "Prolum" power supply should provide the same voltage.
To calculate the second parameter, multiply the power consumption per meter by the length:
7.2 watts/m x 20 m = 144 watts.
However, to ensure stable operation of the lighting, the power of the power supply should exceed this value by approximately 30%.
144 watts x 1.3 = 187.2 watts.
It is important to choose a power supply with a power rating that is not lower than the specified value. Using a power supply with lower power can cause the LED lighting to overheat and fail. On the other hand, installing a weaker power supply may trigger the protective system and render the LED strip non-functional.
When selecting a power supply for an LED strip, it is important to adhere to the correct voltage and power parameters in order to ensure reliable and safe operation of the LED lighting throughout the entire lighting project.
Requirements for a power supply for an LED strip
When choosing a power supply for an LED strip, there are several requirements that should be taken into account:
- Waterproofing: If the LED strip is intended for use in wet conditions, such as on an outdoor terrace or in a bathroom, it is necessary to select a power supply with the appropriate level of waterproofing. Make sure that the power supply has the corresponding protection class, such as IP65 or higher, to prevent damage from moisture.
- Power Margin: It is recommended to choose a power supply with some power margin. This will ensure stable operation of the LED strip and prevent overloading of the power supply. The power margin can be calculated by multiplying the total power consumption of the LED strip by a coefficient, for example, 1.3.
- Trusted Brand: Give preference to power supplies from well-known and reputable brands, such as "Mean Well" or "Prolum". These manufacturers are known for their high quality and reliability. Power supplies from such brands often have the appropriate certifications and provide stable power for LED strips.
- Purchase from a Reliable Store: It is important to purchase the power supply for the LED strip from reliable stores specializing in lighting and its components. For example, the store "Artled" offers a wide range of lighting products and components, which ensures the possibility of choosing the optimal power supply for the LED strip.
By adhering to these requirements when choosing a power supply for an LED strip, you can ensure reliable and safe operation of the LED lighting, as well as receive support and a quality product from trusted manufacturers and stores.
