How big of a power supply do I need?

You need to find the right power source for your LEDs, whether you’re building your LED fixture, repairing or retrofitting an existing institution, or buying a new fixture. You’ll need a constant-current LED driver and a combination of a constant-current power supply to keep your LEDs working correctly. If you want to plug your LED power into an existing outlet, you don’t have to worry about violating building codes.

Here, we’ll show you how to calculate the required output power and choose the right LED transformer. In addition, you know some other criteria that are important when choosing LED transformers. It is important to know the input voltage and be sure that it meets the requirements of the product.

As with most light sources, the power consumption of LED spotlights is specified in watts (W). You can find this in the packaging or printed on the light source. You calculate the general rule by multiplying the watts by the meter, the strip length, and the strip you are running.

In addition to the current regulations, can operate LED strips with more and more LEDs per meter. Still, to achieve the highest power of an LED meter, the total length of the connected strips must be limited. For an LED with a 48-watt meter, it is recommended to run a maximum of 10 meters with a single 60-watt line, and for a 96-watt meter, you can only run 5 meters. If you use too many strips to maximize the driver circuit, the life of your LED strips will be cut in half.

For an 85M LED strip, the power consumption is 14W / m, so you need an LED power supply (called an LED driver) that delivers 119 watts. For the same 24V cable, this means you need to use a thinner line, and 3A instead of 4.5A amps as you can see above, and a little more at the top to make sure you have a power supply that can handle the load you will be running. This means that an analog RGB strip with 60 LEDs / m will consume a maximum power of 12W / 5M (60W x 5 amps).

Check the specifications of the LED strip that lights to know what length you can turn on before you connect it to the power supply. The input voltage for an LED strip is 12 V. So when the LED is on, 12V DC is used by the LED for the power supply. The operating voltage of an LED strip depends on whether you want to dim the AC side or the DC side of the power supplies.

Once you have determined a sufficient wattage for your LED lights, you should consider what type of power supply to use. Check out the last column for recommended LED power supplies.

Our LED lighting products are highly customizable and come in various sizes, so the power depends on the length and type of LED strip lights you are using for your project. This category includes high-power 1.2V power supplies and waterproof power supplies. We explain how to use a 12v LED strip light and how to choose a suitable power supply.

LED strip lights are not as simple as traditional bulbs when it comes to installation and setup. In addition to 120V LED lights, there are various LED spotlights, spotlights, and other light sources that operate at lower voltages. The 150W, 200W, 350W, and 600W high power supplies are the medium to large installations of LED strip lights.

12v led strip lights

Most LED strips are labeled to indicate either 12V or 24V. Now check the voltage and power supply specifications to match the LED strips. If you have a 24V DC LED strip and want to choose a 120V home LED power supply, it should have an input of 12.4V to 24V output. Since LED strips operate at a lower voltage than DC, they need a power supply to convert AC power between 120V and 240V, depending on the location and the voltage signal you use.

Connect way

It is possible to connect the adapter directly to the wall supply at one end and turn on the LED strip without ever using it. However, if you intend to cut your LED strip into lights in multiple segments, each LED strip comes with two bare wires (black and red).

Make sure you are using at least 80% of the rated power to maximize the life of the power supply and keep it cool and avoid overheating. Remember that power supplies and transformers are connected to the high-voltage grid, not the low-voltage grid. You can protect transformers from water by, for example, placing the transformer in a dry place and using a power box, but it is still a problem if you choose a power supply that is not waterproof.
