When you choose to decorate your house or project with LED strips, you need an LED power supply to drive the LED strips.To get more news about led neon light strip manufacturer, you can visit htj-led.com official website.

In this article, we will tell you how to choose the right LED power supply for led strip lights and show you how to connect the LED strip to the power supply.  1. Basic knowledge of choosing a power supply for led strip 1.1 Why choose LED power supply? High-end LED strips are all low-voltage, such as 12V, 24V, 36V, 48V, etc. These LED strips cannot be directly connected to high-voltage lines such as 110V or 220V. Therefore, we need an LED power supply to convert the voltage from 110V or 220V to 12V, 24V, 36V, 48V, etc., and then we can connect the LED strip. Some customers do not understand this knowledge, and directly connect the 220V high-voltage power to the low-voltage LED light strip. As a result, the LED light strip is directly blown up. 1.3 How to choose the correct voltage?

1.3.1 Ensure that the input voltage can meet the customer's needs The voltage in different countries is different, for example, the voltage in the United States is 120V, and the voltage in China is 220V. We need to ensure that the input voltage of the LED power supply can meet the voltage requirements.

1.3.2 Make sure the output voltage of LED power supply and LED strip is the same We know that the voltage of the LED strip is 12V, 24V, 36V, 48V, etc. We need to ensure that the output voltage of the LED power supply is the same as the voltage of the LED strip, otherwise there will be trouble. For example, if the voltage of the LED light strip is 12V and the LED power supply is 5V, connect the LED light strip and the power supply together, and the LED light strip will not light up; if the output voltage of the LED power supply is 24V, and the LED light strip voltage is only 12V, then When the two are connected together, the LED strip will be very hot until it burns out, which is very dangerous. 1.5 How many LED power supplies are required? 1. 5.1 The number of LED power sources is equal to the synthesis of LED strips in different areas. For example, if you have 3 areas a,b,c, the number of LED power sources = a+b+c 1.5.2 How to calculate the number of power supplies in different regions? Number of power supplies in area a=LED strip powerLED strip quantity/0.8/LED power supply power For example, if the area a needs 50 meters of LED strips, the power of the strip is 14.4W/m, and the power of the LED power supply is 100W, then the number of power supplies in that area = 14.450/0.8/100=9 (pieces). So, this area needs 9 power supplies

1.5.3 How to determine the power of LED strips The power of the LED light strip needs to be selected according to the actual needs of the project, such as whether it is waterproof, how many meters of light strips to be driven at the same time, whether it needs to be dimmed, and whether the installation location is large enough.
