How do I choose a power supply for your LED? How do I identify the voltage of an LED strip? You must first determine the LED strip’s voltage; 12v DC power is the most common for LED strips on the market, while others are about 24 volt DC. You may find the following information in the product description:

• If you’re still unsure, you may always check the product image. For example, it is common for LED strips to be marked with either 12V or 24V.
• Now, verify that the voltage on the power supply specs matches the LED strip’s voltage requirements. We’re fine to go here, as the power source is likewise 12V. 
• Also, ensure that the AC input voltage matches the voltage in your country, etc.
• For example, check the reverse label of a power supply to see if the voltage is indicated there, too.

Find out how much electricity the LED strip consumes.

Before purchasing an LED strip, ensure it has an amperage, watt rating, and color temperature (CCT). W/m and A/m might be included here, just like W or A. For example, if the label says the LED strip has a total power of 24 watts or 4.8 watts per meter. Therefore, 4.8 watts per meter is multiplied by 5 meters. This equals 24 watts per reel; thus, this is correct.

If P = V x A, where P is the wattage, V is the voltage, and A is the amperage formula for calculating the amperage,. An A (amperage) may be calculated by plugging in 24 watts and 12 volts and then solving:

• Twelve times twelve equals twenty-four.
• A has a value of 2.0 amps (A).
• It’s currently known that this LED strip uses roughly 24 watts per reel, which is 5 meters, or about 2.0 amps when powered by a 12V power supply.

After checking the power supply, let’s go on.

• The rating is 36W, which is equivalent to 3A. Because it is a 12V power source, we can apply the formula P = V x A to confirm this.
• In other words, this power supply can deliver up to 36 watts or around 3.0 amps.

We need to look at their respective power requirements to infer that you may use these two products together. People who don’t understand the meaning of wattage and amperage ratings on power supplies may become alarmed. For example, an LED strip with a 24-watt output might be expected to be damaged by an AC power source that pumps 36 watts into it. If you opted to reduce the LED strip in half, would you create a 12-watt LED strip instead of the 24 Watts?

This is why we stress competence and capacity above anything else. There’s no guarantee that a power supply with a 36-watt rating will deliver that much power. On the other hand, the power supply will only provide as much power as is required and will adjust to the demands of whatever is connected to it. However, power supply malfunctions and damage can occur if the power draw exceeds its capability. This power source can power LED strips requiring less than 36 watts.

Decide on the best manner of connecting.

The power supply is likely to include the following type of power connector:

• 5.5 mm x 2.1 mm is the most common measurement for this size. LED strip plugs may not work with 5.5 mm x 2.5 mm connectors.
• Check to see if the LED strip reel has a DC connector.

If this is the case, you can connect the power supply to the wall and the LED strip to the other end of the power supply, and you’ll be good to go. The alternative option is to split up your LED strip into various pieces or, if the entire reel comes with only two bare wires, red and black,.

Adapters must connect the power connection from the power source to the LED strip when using this method. You may connect the free wire ends to the adaptor when the adapter is connected to the power source.
