How to choose the power supply for LED light strips?

1. Purchasing criteria for light strip power supply

The selection criteria for light strip power supply mainly include the length of the light strip, the power and current of the light strip. The specific selection criteria are as follows:

1. Light strip length: Choosing a suitable power supply according to the length of the light strip can greatly increase the service life and stability.

2. Light strip power: Choose the corresponding power supply according to the power of the light strip. The greater the power, the greater the power supply required.

3. Current: Select the corresponding power supply according to the current of the light strip. The greater the current, the greater the power supply required.

2. Specifications of light strip power supply

1. 12V power supply: suitable for single-color and low-brightness RGB light strips, especially for short light strips.

2. 24V power supply: suitable for high-power RGB light strips and long light strips.

3. 48V power supply: suitable for high-power white light strips, and also suitable for light strips that mix white light and RGB light.

3. How to correctly calculate the capacity of the light strip power supply

The formula for calculating the power capacity of a light strip is: length of the light strip (meter) × power (W/M) ÷ power efficiency (%) × coefficient (1.2). The coefficient is 1.2 to ensure safety and reliability.

For example: You purchased a 12V 5050 light strip with a length of 5 meters, a power of 14.4W/M, and a power efficiency of 90%. According to the formula, we can get:

5 (meter) × 14.4 (W/M) ÷ 90% × 1.2 = 96W

Therefore, you need to choose a 12V power supply with a power of 96W.

4. How to install the light strip power supply

1. The light strip power supply needs to be installed in a waterproof manner and try to avoid getting wet.

2. Before installation, you need to check whether the rated voltage of the power supply and the rated voltage of the light strip match.

3. Clean the heat dissipation holes of the power supply regularly to ensure the heat dissipation effect.

In short, it is crucial to choose the appropriate light strip power supply, which can not only extend the service life of the light strip, but also ensure the brightness and effect of the light strip. If you are not sure how to choose a suitable power supply, you can consult relevant professional technicians.
